Again the worst Service I have to experince.

Good day. I made a payment of the arrears amount on Saturday Morning. I am due for a refund from Pinnacle Marketing. apparently MTN Customer Service has still not confirmed to Pinnacle Marketing that my MTN account is Up to date and my refund can be processed. It's Thursday, The payment was done on Saturday at 07:30 am the proof of payments of the arrears was sent to the insurance and the MTN customer service. Why is it that we need to first complain to get good client services from these providers which we bring business too???!
