very bad customer service- Mis-selling I am very disappointed with O2 customer service. I am a Vodafone customer and I wanted to switch to O2 Since Nov 2023. I spent 2 hours speaking to O2 team Nov 2023 and they said they will send me a sim-Card within 5 working days. I didn't receive any sim card I had to call again and chase for the sim card, 02 team said it might got lost with Royal Mail so we have to request another Sim card to be deliver to you but unfortunately the deal has been expired as it passed the one week period which I wasn't aware of and I never heard of a network company keep changing their offers evry week , so I had to go through the whole process and spend another 1 hour & 40 minutes. Again I didn't receive any sim card from O2 so I had to call and chase again on the 24th of Dec for the Sim Card, every time I call o2 team have different excuses and different story. The last contact I did on 24th Dec2023 which took me another 2 hours to spend, the offer was 125GB , UNLIMITED CALL& TEXT AND European roaming for one year which is 12 year of £18 Only. what I don't understand I just received the Sim Yesterday the 11th of JAN 2024 , HOW come O2 charged me £19 on 10th of Jan 2024 for something that I didn't receive/use and I been chasing for a months plus the contract is £18 and they charged for £19 which mean extra Pound on the top of my contract plus I never used their service ?? and when I called O2 customer team yesterday to ask them why I have been charged they hang up the phone on me twice and one of o2 team said my contact is for 2 years not one year this call miss-selling Imagine how many hours I spent with O2 team to cancel this contract, they kept transferring my line to one another and at the end they hang up the line and never called me back again. and every one of them tell you different lay at least when you lay to customer write it down in you system so when one of your team pick up the case they should stick to the same lay. Their customer team doesn’t listen to customers and I ask them to transfer the line to complaints department, they said they don't have a complaints department. very bad team and I will never recombed o2 to anyone
