Why can't you provide proper customer support?

I cancelled my two vodacom contracts: 1 Tablet 1 ****le with data As far as I know there is no issue with these two cancellations and the sim cards were switched to pay as you go and never used since. Then I've agreed to a telesales offer from Mondo for 2 R207Z mobile wifi rooters, but when I received it, the items were not as the sales person (Turon) described. I used my rights and enforced the cool off period. I returned the goods and called Lizzarine to confirm that the items were returned and received a reference number (57830). For the last few months I kept getting messages that my accounts are in arrears, but when I call the Vodacom retention department, they refer me to accounts and vice versa. In one instance I went into a Vodacom shop in N1 City to seek assistance, but they could not care less and referred me to customer retention. The first few times I called, the phone was picked up for a few seconds (I can hear the chatting and the laughter in the background) end then the call is ended. When I eventually came through I was informed that I do not have any active vodacom contracts and that they will look into the matter, but as expected, nothing happened and I still received messages that my account has been handed over, followed by messages from debt collectors. My credit record is perfect and I do not have time for this incompetence. The last straw was when Vodacom just took money from my bank account yesterday! How can that be possible! I've tried everything to get this sorted out and no one on Vodacom's side care to do anything. Today I called customer retention again and Nomcebo referred me to Cancellations. I spoke to Bongani and he said that the systems are down and referred me to Legal. I called legal and when requested to enter my ID number, I get feedback that my ID number does not exist!!! HOW DO YOU WORK LIKE THAT??? I need assistance to sort this issue out and that is why I came to this platform. My Vodacom account number is I***
