Vodacom quick to take money, but not quick to deliver any service

Good day, Ive been experiencing the worst service when it comes to the vodacom team, especially with Fibre. Upon applying for Fibre 27 December 2017, i was given the run around for months for installation to take place which then only happened April 2018. After a week, my fibre was down and support took 2 weeks later to come and fix it, to which i then cancelled my contract SR180 ********** 33. It has been 4 months later and vodacom is still deducting money from my account and whenever getting through to the customer support i am told that my matter has been escalated and that a superior by the name of Warren will contact me and credit back money taken from my account, but no contact is made. I hope there is actually somebody reading this that will be as quick to respond to this as quick as vodacom are to deduct money from my account.
