Hollywoodbets using my details without my knowledge

My privet number that is fica on my name and I am paying for is registered on Hollywoodbets under some one else name. Hollywoodbets customer service does not want to remove my number from the account or the profile it is linked to. They are telling me it is private and then drops the phone in my ear. No one want to help me. To use some one else number that is fica on there name and is paying for the number every month is ***** but Hollywoodbets people does not see it in that way. It is the same as using some one else I'd number. They are rude I phoned like 8 times no help gust tell me that they can't it is linked to some one else and then drops the phone in my ear. Greate work Hollywoodbets!!
