Data bundle contract not cancelled

Vodacom doesnt even deserve a star. I called 1st week of January 2021 and spoke to Sophokazi from retention department, told her I want to give one months notice to cancell my data contract but said u must call 1st week if feb to do so as my contract ends on the 15th of feb. I told her not according to my contract, my contract states 1 months notice, she said i must call 1st week. Called last week on the 4th and spoke to a gentleman who said will escalate matter to Sophokazi manager as she didnt follow procedure and I will get sms within 48hrs abt the cancellation of my contract and nothing. This morning I'm calling and the lady line said to me she will escalate again as there was no feedback.i must call again after 48hrs to follow up. One of the reasons why I'm leaving is the poor service I'm getting from vodacom. The service is shocking.
