Disgusting Customer Service

‪HELP !!!! Month before my son had left SA for a fellowship overseas, he contacted MTN, requested termination, the amount they requested was ridiculous amount that was the contract x2. So he sent an email stating that if the contract was to end in November could they confirm this‬. Today I called to confirm this and was told that unless he calls… taking into consideration that MTN take between 12 - 15 minutes to answer a call, and a further 10 minutes to refresh the system. He has sent emails. Provided me with all the required information. They want him to make an international call so he can cancel the contract….again or it will automatically fall under Top up which will cost more, as it will be month to month. WAY TO GO MTN….now I know how you make your money
