The sad sad tale of Telkom's absolute indifference to customer complaints!

My account was increased in January without my agreement. I have had a few phone calls and have also visited their Tokai branch on at least three occasions. My complaint was eventually referred to a Regional Manager. I cancelled the contract in February and paid my final account in March. I am still being billed both the excess amounts from January as well as the monthly subscription. I have probably sent Telkom at least a dozen emails. They are absolutely pathetic and treat customers with contempt.
