Ref.Cell C Sp *** - Debit order charges for a lost cellphone for 4 -5 years now and I want my R49 times whatever the years back into my account - angry!!!!!!

I had a second contract for my son 4-5 years back and the cellphone got ******, paid it off and now i get a charged of R49 on a monthly basis in which I have spoken to a number of people in CellC for it to be stopped to no avail and i want all my money back that they are still deducting for nothing. I am sick and tired of this issue as there seems to be no one listening at all. I don't have another choice except to come here hoping I will be heard.
