Dealing with Telkom is a nightmare

I've had a Telkom prepaid landline for more than 10years on the same number & pay the annual subscription religiously. I paid the 2018 subscription in June & even loaded airtime. My line was suddenly suspended & cancelled regardless. I have been calling Telkom everyday to resolve this & absolutely no one can help. I keep being told to call different numbers & if I'm lucky to speak to someone who'll listen, I'm given a reference which it seems means nothing at Telkom because they either "can't see anything" or refer me to 10213, 10218, 10 ********** 7... I've called them all from my cellphone. I GET CHARGED FOR THESE CALLS. Ive paid an annual fee for a cancelled line! I've had the worst experience and feel Telkom is the worst service provider. Totally useless!!!!!
