bad customer service

took my iphone 5c for repairs at the randburg square mtn during the strike period, have done most of my correspondence with through the service consultant at the walk in center.I have requested that they give me the quotation for the amount that i would need to pay for the repairs to be done on my phone as well the banking details to make payment as was not allowed to pay at the walk in center but they failed to do that and they tried to communicate with at any chance.When calling the repairs center i get consultants that are not willing to help at any point when discussing the problem that i have, i was wiling to make payment of the R330 evaluation fee done on my phone as they never assisted in quoting me for the actual repair charge on the mobile phone.I am truly disgusted with the service that i have received from Mtn as i have been with them for years and have a contract with them that i never miss a payment. They increased their debit fees without consulting me as the customer who pays the account and there after they fail to even produce me with the monthly statement after increasing the monthly payment.Mtn truly has the bad service ever from the network company's.BAD SERVICE
