Debit order still occurring 3 months after cancell

I have repeatedly visited Ellen at Altech Autopage East London, Beacon Crossing branch, to query why the debit order continues so long after cancellation of contract. Each time Ellen emails head office and gives me the following reference number: 526157. However, the debit order continues. It is now 4 months since I cancelled the contract with no success after numerous complaints from my side. I have tried calling Eldrin Regard at the JHB number *** - I managed to get through to the receptionist, Clementine. I told her my complaint yet Mr Regard fails to return my calls. I am totally disgusted by their lack of service. The numerous trips into town and JHB phone calls are an extra expense, over and above the debit order which continues to come off my account on a monthly basis. Enough is enough!
