Ultimate oomph bundle - still being billed incorrectly
Back in January I upgraded my cable package to the Ultimate oomph bundle with unlimited SIM. I told the advisor that I already has Virgin mobile SIM which I pay for monthly and he said he will transfer the account over so that I receive only one bill, for the oomph bundle, which includes mobile. However my mobile was never transferred over and I have been billed incorrectly as I am still receiving a mobile bill every month. I contacted virgin on multiple occasions from January to today. In the past two weeks I have spoken to Virgin Mobile, Virgin Media, the Oomph sales team, and each time they say it's another departments issue. I have tried using the text service as hold times have been 2+ hours, only to be transferred to someone who says it's not their department that can fix this.
I have been charged wrong and they have not refunded me. I have been told only a specific team can fix this, but that they don't have a number to call, and they only do callbacks. I have been promised call backs from last week but never received these - I have called to chase and each time they say give it another 24 hours.
