Virgin Mobile charging me for contract I cancelled

I had an account with Virgin Mobile in 2011 and decided to terminate the contract as was being billed for airtime that i was not using. i spoke to a staff member from Virgin mobile who informed me what amount was outstanding (R413) and also the amount for a handset fee that I had to pay which came up to a total of R413.00. I still have the name of the staff member as well as emails that i sent with the proof of payment as well as a request that he send me an email stating that my contract had been cancelled. I got no response from this gentleman despite sending 3 more emails after that. After paying i received no more statements from Virgin Mobile up to today 2015. i was therefore shocked to receive an sms from a company called MBD LCON saying my account had been handed over to them and that i needed to pay a certain amount (the amount changes everyday). i demand that my name be removed from this database and that Virgin mobile rectify this IMMEDIATELY or i am contacting my lawyer. I will never ever subscribe to any service / product that is associated with Virgin Mobile again and will be cancelling my children's accounts with them effective immediately.<br> <br> Abongiwe
