Very poor and bad service 1

I called vodacom on the 14 April to cancel my expired contract which ended on the 11April and refused an upgrade and was promised an sms or email confirming cancelation which I didn't receive, then I kept on receiving calls to upgrade and told them that I did cancel. On the 26April I received another call to upgrade, I then called again and to my surprise there is a new contract of data on my name which I didn't approve, I requested cancelation and reversal of new contract I didn't approve, and requested reference number for cancelation, there was no reference instead a reference for a call, I requested a supervisor and was on the call for almost 2hrs with no resolution to my call. I dropped the call and the consultant promised that the supervisor will contact me in an hours time, not at all. I was promised that my query is escalated to back office for cancelation and reversal and I will get an sms or email in 24hrs confirming that. Now by this time 27 April 18:50 no such email or sms. This morning I decided to go to vodacom Wonderpark and spoke to Lesley, he was really helpful I called contact center and to my surprise the consultant that I spoke to yesterday Lindelwa never placed an escalation for cancelation. What is happening here vodacom, who is fooling who here. This is a bad service. Today I spoke to Nickeel and promised an escalation, I even got an sms for cancelation and a reference. I need this to be urgently attended to. I have been with vodacom for solid 25yrs but your service is very poor and bad. You must also tell your consultants to stop chasing stats and sales with your customers. I'm very disappointed I will never advise anyone to take any product with you guys out my experience with you after being a loyal client of 25yrs. I will be waiting for my final cancelation confirmation and I am done with you guys, if not I will take this further to Ombudsman and consumer commission.
