Poor Service!

My grandmother is old-school with a landline. She pays every month through checkers. One payment was missed as I think the teller at Checkers punched in the wrong number or something and Telkom was quick to issue a legal letter to her. We have sorted out this matter by paying the outstanding amount and they still have not bothered switching her line back on for weeks now. No bother replying to my mails either. Happy to take their money! Hopefully this way, I will receive a response....
