Bad bad bad service!!!!!!!!!!!

Our data-contract has expired in July 2018. Since then we tried to cancel our contract but with no success. The cancelation department, according to me, must be the most *********** department in the whole of Vodacom. After numerous calls to this department, we still cannot cancel our contract. I can give names, dates and times of phone calls to proof this comment. Promises were made, but still no cancelation of the contract. And for almost three years, the monthly payment is going of our bank account, AND NO PROBLEM WITH THIS. Is there anyone in Vodacom that are competent enough to cancel our account. I wont recommend Vodacom to any person at all.
