Recalcitrant, Abhorrent, Appalling, Inept and Haughty Vodacom

I settled my 3 contracts on my Vodacom Acc No I***-1. I sent proof of payment to Cancellations and Customer. Vodacom Customer called my on a phone that was almost dead flat. Instead of calling me on my primary number for any follow-up, Vodacom Customer claim they are unable to reach me. The appalling customer service from the inept call center agents at Vodacom contributed to my decision to part ways with them. Is too much to ask for the contracts that I have settled to be terminated? Never again will I ever do business with Vodacom. NEVER!!!!
