MTN South Africa service is pathetic

My wife app**** for a R500 data contract from MTN early September. Calls go unanswered completely, emails take days to respond to with a simple yes or no, contract was eventually approved but then she had to wait for delivery, courier arrived and she was out, said they needed her biometrics else could not deliver. Anotheek later delivery was made to her in person without biometrics....device does not work...was reported online, in email and in a store, another week later and still nothing...will probably also be billed for 2 months now...pathetic service....and try to find a complaints number online....Good luck She even tried copying in their CEO in a mail with the hope that it would speed up processes, even that went unanswered and without acknowledgement. Absolutely shocking experience, probably make too much money to care about little businesses.
