I have done this many times.
At the moment due to my suggestions the 3 accounts I seem to have had have been deleted leaving just one. In some ways a result after months of trying since March 27th I can manage emails. However, Bt tinkering without informing me mean I have to keep resetting my password.
My promised prices have rocketed and not been upheld now I have to chase this to get a refund. Compensation is derisory and doesn’t even cover the months my service hasn’t worked or been in accessible to me. The guide has admitted I have been mis-sold.
I want to be treated fairly. Promises kept and a working service???
