Pathetic customer service

I had a contract with this company for 2 years. They debited my bank account every month literally as my salary went into my bank account. In December my line was disconnected and upon my calling them I was told that the line was changed to a Prepaid line as the contract was due to end 31 Jan 2019. However I also did not receive my airtime allocation for Dec 2018 and Jan 2019 - to date. I have made too many calls chasing this matter up but they simply push the buck from one consultant to another and their managers are always in meetings - nobody ever calls back. I was assured that i would receive the airtime at the end of Jan and when that didn't happen I was told 09 Feb. Still nothing.

The customer service is despicable to say the least!
