Still no final bill or refund

[Dave75]

I was told I would receive a final bill within 14 days of cancelling my account and porting to another provider. It is now 28 days later and still nothing. 
I have no access to my O2 account since cancelling and therefore cannot see any bills either in the app or on O2 website. 
I was told any refund due would be paid as part of final bill automatically. This has not happened. 
I have wasted time with O2 customer services. I have waited. Still nothing. 
I have become so frustrated I have raised a complaint through the O2 process. I received a reply confirming a 7 day response. It is now 9 days later…..

what more can I do?

I just want a final bill and my refund.

I’m with Tesco now so fingers crossed the good service level I received when I joined them continues. And that I never need to call on support at all of course.

Good luck with Tesco Mobile, they do have a good reputation for Customer Service although I have not tested that personally.
