Telkom Bullying It's Contract Clients

Absolutely ********** service delivery. Overbilling even though I'm not utilising half of my allocated data as I'm constantly using WiFi at home. After numerous times informing Telkom customer service centre that my debit order date be changed from month end to the 2nd of every month, they totally ignored numerous attempts of mine to change it. Telkom ignored my requests and subsequent plea but instead proceeded to charge me for rejected debit orders. Their services are appalling to say the least! I would not recommend them to anybody, not even my worst enemy!
