Horrible service from MTN

I have had the most poor service from MTN. I bought a Pay as You Go router. I made the upfront payment as well as prorate which happened at the beginning of August. They then made a mistake on the debit order and tried to debit on the 15th. I realised this was happening. Contacted them and changed the debit order, paid the amount owing and went into MTN to pay the reconnection fee all on the same day. I have been on the phone for literally two days and cannot get reconnected even after numerous reference numbers and requests to speak to supervisors and managers. Burkina absolutely refused to let us speak to a supervisor or give his surname. Valerie promised all would be sorted but it was not. I am so very tired of awful service. I just want the WiFi so that we can watch the rugby.
