ABSOLUTE SCAMMER. ***DO NOT USE*** I’m so disappointed we didn’t read all these reviews before engaging his services. Kosta has basically used the same bullying tactics as described in these reviews. This is very REAL. Please take our feedback seriously and use other more well known cryoshipping companies. Kosta is basically asking you to write a blank cheque. MO: 1. He sends a quote lower than competitors. 2. Phones within 1 hour of quote to discuss costs and proceeds to ask you to accept a significantly increased amount (20% higher then original quote). Says that this increased price takes into account any Covid incidental costs. His language and tone is to get you on side. 3. He sends you an invoice for deposit and confirms delivery will take place within 2 days. 4. Once deposit received he goes radio silent, doesn’t reply to emails, text messages or voice messages. 5.When he finally surfaces (for a brief moment) he proceeds to lie about his whereabouts and travel plans and before you know it you’re in this crazy nightmare desperately chasing him to find out where your precious cargo is. 5. He goes radio silent again (we think he does this make one feel even more desperate). 6. Almost a week later he makes email contact and gives you very little information and more excuses (none of which can be substantiated even if you call him on it). If he doesn’t like your questioning he just ignores it completely. 7. After further radio silence and when he thinks you’re about to to cancel, he notifies you that he’s on the flight and making his way for delivery. 8. Within 24 hours he is suddenly demanding 40% more than the original quote and threatens to charge you a penalty amounting to 11% of original invoice (on a daily basis!) unless you agree to pay the final amount immediately. He refuses to deliver before full payment is received. 9. He then tells you he’s the only one able to deliver during Covid times so good luck finding someone else. He also sends you a fabricated table with associated costs. He does not provide you with any expense receipts or actual proof of expenses. He tells you he’s had to take more flights than expected and uses travel restrictions fir this yet he is unable to provide travel tickets proving this. 10. He finally delivers when you pay in full but he leaves it to the last 30 minutes of the day (just before the lab closes). He is utterly despicable, preys on the weak and vulnerable - basically holds you to ransom before delivery. He uses extortion/blackmail to get what he wants. Words of advice: If you are currently in this situation, cc your clinic and fertility specialist in all emails. The only thing he cares about is his reputation with the clinics!!! Because we did this, we at least managed to receive confirmation from our clinic that he has actually arrived at the delivery destination and we managed to revive confirmation from our clinic that our precious cargo was in good condition. If we hadn’t of CC’ed everyone, he would have insisted on prepayment in full even prior to delivery (despite the delivery already being 2 weeks overdue). Hold your ground!!! Make sure that your clinic knows that they are not to email him without you being CC’ed. He likes to play everyone up against each other. Keep everyone in the loop all the time. He doesn’t like this as he really needs to communicate when this happens. He likes to discuss any new or additional costs verbally, never by emai. He LIES LIES LIES. So get everything in writing via. Do not take phone calls - rather tell him to email you instead. Stay away from text messages. Stick to emails with all parties included (especially your clinic na fertility specialist if possible). Do not accept any agreed change in terms and conditions unless he puts it in writing. He uses the terms of conditions to justify why he can charge more. I would basically be saying to him that you will not agree to anything more than 20% of what has been quoted and state that when you sign it. This guy is a shark. Be very careful and be prepared to loose your money.
