Telkom mobile is a terrible service provider

I am a loyal client of telkom mobile who has never skipped any debit order payments nor failed to meet my contractual obligations. Therefore they introduced an increase in spending limit that they failed to promote to all clients effectively and failed to get consent from me as a client on this matter. They are now forcing me to pay an exhobitant amount which I did not CONSENT to. They do not even want to go out of their way to satisfy clients even though the fault ultimately was theirs. They are a very oppressive company and take their clients for granted! I will never refer any one to telkom mobile and will take my business to a company that does not impose promotions on clients and are not oppressive to them. I THOUGHT The apartheid era had ended but clearly with telkom it's still very much in existence!
