Lack of service, pathetic turn around times

i recently changed banks and called in to change my debit with MTN, since it was close to debit date i EFT'd the payment and sent them the proof of payment that was on the 31 August 2015 at 09:32am. Till today 23/09/2015 i have been mailling and calling MTN to confirm why my line was suspended if my proof of payment was sent and its the account details they gave me. It is a major dissapointment that they are so quick to disconnect my line yet my query they dont answer. I am complaining here as this would be the last time i will be using MTN i will be switching me and my families phones to a different network. Thank you for your **** service MTN.<br> and they can go check their references<br> #***7<br> #***5<br> #***7
