No profile for me but my account is handed over!!!

I took a contract online with Vodacom in June 2016. I then cancelled the contract within the 7 days period and Vodacom sent Rams couriers to collect the device from me. I called Vodacom on numerous occasions to have this contract cancelled as Vodacom was still debiting my bank account. I was told on more then one occasion by some of the consultants that they cannot pick up my account as it was on a new system and their system was not yet upgrade. Eventually i was told that as far as he can see the contract was cancelled. Today 29/03/2018 I go i instore to get a Vodacom contract and im being told that my account was handed over to the legal department. I then called the call Centre and spoke to the legal department, accounts department and after sales department and no could assist me saying that they cannot pick up a profile in my name.How does Vodacom hand me over when they have no recollection of what device i took?!? Now im being told that im listed on the ITC!!! Vodacom need to sort out their sh*t. I have returned their device and according to me this account was cancelled 2 years ago.
