Can switch up, harassed by bills I don’t owe . Worst network ever!!

Hi

im after some advice in case I’ve missed anything I should be doing. 
it all started several months ago when I started getting bills right after I had paid my monthly bill. I’d ignore them at first thinking they just needed to catch up but they continued. Even sending my account to collections!!! I’d phone up each time and try and speak to someone to explain my case as they didn’t believe me. But each time a manager would end up crediting my account or someone in payment management would but the worst thing was they were sent while I was grieving my mother who had passed away my partner was going through cancer treatment. 
the final straw came when I attempted to switch up my handset. Shouldn’t be a problem I thought.  It’s been 90 days since I last switched up my phone. So I contacted o2 by phone. Not possible they said.  I was enraged.  Why??? I asked. You guessed it. Because I owe money on my account yet again!!!!! This time it was £5.  No idea where if was from but it was there. So rather than argue over £5 I paid it. But it didn’t clear. So I paid it again. Still it remained. Even they tried to clear it, didn’t work. This has been going on for weeks now and in s stuck. O2 won’t help. It’s like they have given up trying to fix it. I however am stuck paying  for a service I can’t use. I have sent them a complaint to which I have an acknowledgment but after many months of waiting no final outcome has been received. I have finally gone to the financial ombudsman and started a case there. But I know that is going to take a while. Is there anything else I can do? Anything I’ve missed!? Thanks ☺️

You seem to have done everything you can but we are customers like you so have no access to your account.

Sadly you have to persevere with O2.

This looks like something you’d need to call O2’s customer service team about – give them a call on 202

or 0344 809 0202 (or Payment management number -0800 902 0217 or 0800 032 5302 )

Or you can message O2 on social media on Instagram https://o2uk.co/O2CIG), Facebook ( https://o2uk.co/O2CFB) , Twitter ( https://o2uk.co/O2CTW)

. Try social media, they have a better reputation, although you will need to keep nudging them
