disgraceful cusomer service

called mtn -10.9.15 to query bill contract - ***. I maintain when I app**** for the contract telephonically - I requested a top up option not an open line. in spite of being promised an answer on the 10.9/2015 and various correspondence thereafter with kresan govender & slindile mdubo , this has not been resolved. I was promised twice that the call recording would be available to listen to, in both instances this did not happen. I went to MTN at Liberty Mall (PMB) the attendant could not retrieve the msg. I then went to MTN in Umhlanga - the recording was incomplete. I have emailed Slindile ? 3 times since her last promise on the 27.10.2015 that another call would be logged. She has not even had the decency to reply. this is extremely frustrating to have such poor service. Hopefully some day large, arrogant corporations like MTN will be fined for poor service as well!
