Good day I am tired of MTN poor service even though I have been a loyal customer for the past 20 years this time around MTN have system error on system they have capture my two contract wrong and I have provided all the evidence and my contract are expired already which means I can only pay month to month fees to my surprise I have to MTN store as well as contacting the poor customer service with all query reference SR 1-*** and this affecting my credit profile because have been advise by one of best MTN consultant at MTN STORE not do the payment until the contract terms has been fixed because I have evidence the contract on the system is wrong and hard copy shows my contract is expired. This time around I am going to change my network please fix it before I take legal actions with my attorney because this is daily *******.
