Disgusting and *********** Service

I cancelled my 2 year contract with Vodacom in January 2016. Well in time before my due date which was 20 February 2016. I filled out the Migration Quotation *** on time and emailed the [Email Removed] [Email Removed] [Email Removed] and asked them to confirm they have received my form and that they understood the instructions. They did. I received an invoice for this particular mobile number via email today for the month of March 2016. I have been purchasing pay as you go data which has not worked from the 20th February 2016 up to today, and paid R180.00 to have my phone repaired, number registered and all the online data I have purchased credited to my phone. I was on the phone for 20 minutes and was put through to the accounts department twice, cancellations department twice, contracts department once and then spoke with a call center agent. The person on the chat online, terminated the chat when I explained my problem. What kind of service provider are you and how do you train your staff?
