Disgruntled!!!

Worst mobile service provider EVER!!!! - Tried changing my banking details with Telkom, - spoke to a consultant who took my details but never changed it on the system. My debit order bounced, - Im getting charged a ridiculous amount in fees. My account got handed to legal now im getting threatening messages. Try calling the call center, - good luck trying to speak to someone that actually knows what they're doing. - Because, then i get told change in banking details takes 3MONTHS to take effect???? Why was this NOT communicated so I may make alternate payments!!!! - DISGRUNTLED with the underwhelming service.
