Telkom - **** service at a pricey rate

Not usually one to name & shame but honestly the service I have received from Telkom is **********. From not being able to assist me with why my eft or mobile banking payment would not work or on how to pay via Woolworths (which you advertise ) to me receiving a statement 2 days after my original statement giving me an amount of 600 something extra due because app you increased my spending limit or airtime. Firstly, I have a capped account for a reason. I have never requested the increase nor authorised it. Then you say you've sent an sms informing me its been increased. I'm sorry I must of missed the memo when you by law had the right to increase my spending limit which I specially had capped without consulting me or giving me an option to say no. And no sending me an sms is not good enough because half of the messages you guys send I don't open because it's a bunch of advertising . Also- you don't increase something and then tell a customer they have the chance of deactivating it themselves. You flipping give us a say on the matter. Nevertheless I will be cancelling my contract with you and needles to say so will everyone else in my household. You guys are the definition of terrible customer service. You have no regard for your customers .
