Found an excellent upgrade deal on their website that had an upfront cost of £50 which I had reduced to £30 as I had a valid discount voucher code. Gave thew company my card details so they could take the authorised amount of £30..... but instead they took £180.....and just before Christmas too !!!! Luckily I took screen shots of the original deal as seen on the website and I had 2 e-mails (order confirmation & order completion) from the company that confirmed my only upfront payment should have been £30. What next occurred can only be described as shocking Customer Service and it was such a struggle to get the unauthorised amount of £150 refunded. Their promises of getting back to you (e-mail & phone) within certain timescales were broken on more than one occasion! EVENTUALLY after 4 phone calls of about 30mins each (costing approx £7 per call!), 3 online messages via the message service on the 'My Account' part of their website, 3 afternoons of my time, a report to my Bank to open a dispute case to recover the money and a call to Citizens Advice (who are referring them to Trading Standards); we were refunded £150 !!!!!!! I'm extremely annoyed that I have been thoroughly inconvenienced at one of the busiest times of the year and also that despite my rightful refund I am out of pocket because of calls/time, etc. I have also had to pay for a product, for a period of time, that I was advised by my bank not to use until the matter was resolved! MY ADVICE IS AVOID THIS COMPANY - THEIR CUSTOMER SERVICE IS APPAULING !!
