Disgraceful service

Hi, I have been having a nightmare with a Mobile content subscription blue label being charged to my RCS account - RCS keeps referring me to speak to blue label and after numerous phone calls and emails this subscription is still being charged to my account even though I have never subscribed. Myt account was paid off for months before this subscription now appears on my account. It is absolutely disgraceful that I get threatening SMS's each day but get no feedback when asked when I agreed to this subscription.
