Incorrectly billed: my old issue not sorted after 2months

Ok I decided to at least give 2 stars this time. So after all the drama to get fibre and being assisted so good by Olivia, I now am paying for 4 fibre deals. They were supposed sort it all out. Now Im still sitting with 4 new routers and I have been complaining from the beginning about this and NO ONE has made any effort to collect them from me. This better get sorted out immediately and my account credited. I think this is the last straw and maybe moving on to a better service provider who's admin and callcentre know what they are doing. And the best of all is if I decide to only pay what I am supposed to pay they will stop my fibre until my account is up to date. Olivia where are you now please sort this out for me.
