MTN error.

Game Archery Elite on Google play One of the payment options on google play is to add products, upgrades required for the game to your MTN bill. My profile settings on MTN, such as usage limits, sufficient airtime is all correct. According to the "MTN champion" my profile is all in order. I still get the error "Apologies but your request has not been actioned due to an MTN error. I have contacted MTN and query*** was opened. The "MTN champion" that I spoke to did not have a clue what the issue on my MTN profile could be and suggested that use a different payment option. This case was closed but the issue could not be resolved. I am still experiencing the same problem. How can a query be closed if the issue could not be resolved? I need a MTN champion supervisor or manager to take up this issue and get it resolved ASAP! I also need this supervisor to contact me otherwise if I do not get contacted or this error on my MTN account profile fixed, I will take further steps to have this published in the media and NCC, ICASA will be contacted. How can a query be closed without solving the issue? Queries get closed not caring if the customer issue get sorted. Case closed and forgotten!
