Fed up of **** service from VODACOM

I gave notice of cancellation of my contract in Jan 2020, my contract expired in Feb 2020. Vodacom took money from my account in March even after I have cancelled the debit order. I was told that the person I spoke to did not cancel my contract. I have sent emails and made telephone calls to them - Till today my refund hasn't been paid. So its my fault that their consultant is ***********. Vodacom knows how to ******* people. And for me to have to keep begging for my money is not right at all. They don't even deserve a score of 1 considering that I had to be without internet for 3 months as a result of a faulty router. I had to take them to the Ombudsman for them to replace the router. Their service is very bad
