Poor service, not efficient

I have attempted to close my contract and migrate to prepaid on the 29th June at MTN south gate mall, I was firstly told my ID copy is not clear enough, brought a clear copy, then I was told I will be contacted with feedback as soon as all is processed or if they need any other information, I was not contacted, tried to contact store on *** phone just rings no options to leave voice mail so my call can be returned or anything, eventually I get hold of store I am told only person who helped me with the application can assist me, waited for her then give her REQ no which is REQ: *** she said she will get back to my close of business to date no feedback I ended up getting my normal contract airtime on the 14th July, I called again store spoke to her they told me I will be reimbursed and will not pay for normal contract only for the airtime to date still no feedback, get to store and no one is really interested in helping me as I am closing my contract getting passed from one person to another for feedback, eventually left the store hoping I could contact contract support on *** to complain but no answer as always MTN is not worried about how there customers feel
