Hello I have a problem with Blue label the have sign me into a mobile content subscription Blue label without my knowledge and they have been doing it for years with out my knowledge because I just recently found out I have an outstanding amount that I don't know of and they said their going to cancel the contract but nothing has change in that I have statement of this ******* transaction.I have contacted Blue label about my cancellation but no feed back since 3 March 2025. Yesterday I went again for an update the said there still reviewing my issues.But at the sametime there still calling me that I still owe them.
