Haven't used my contract phone in almost 12months as the signal is almost none existent and data speeds would barely pass 10kbps. That's kbps mbps! Once my contract had ended I called to cancel to be told I will be charged an additional 30 days at full price due to cancellation notice! So much for the 24month contract, more like 24months and 30days contract. After going through cancellation with a rude and unhelpful advisor I was passed to customer service to check my final bill cost and after waiting another 10minutes on hold i was told no cancellation has been put through and no notes written. I was then passed back to retention tram to cancel again and again had to go through security and start all over again! This entire process has been shocking! Worst company I have ever dealt with. I honestly don't understand how they are still in business! O2 used to be the company to use, they are now very clearly the company to avoid.
