Poor service (network and Customer service).

I've done an online contract application with Mondo for an MTN A33. the phone was delivered at my work place without a sim card. Took the phone to Alberton City MTN , had a dispute before they can finally take the phone back. While i was waiting for the Cancellation to go through, my Account was getting Debited since from Last Year even now i am still waiting to be credited the Amounts debited from my bank account . Each an every time i call MTN i get given a Ticket Number/ Ref number and i still need to explain myself what i have been explaining since from last year. Just wondering why ain't they taking notes that they can store on their system for the other person to see who happens to check the query. It's so Disappointing for a Big Company like this to treat Clients (new/old) like this. Kindly please offer Training To your so call Bozza Network Consultants or Update your systems. One last thing ,Kindly please do something regarding the Network Reception all over please. Data getting finished without no results. Network is Poor.
