Poor bad service

Good day<br> <br> Please be advised of the poor pathetic service I have consecutively received from your stored with regards to my contract that was transfered or handed over to you by nashua mobile.I have made payments to the previous bank details I was told a reversal was to be made and I have been promised and sent emails by mtn customer care that my query has been resolved two times not knowing how without me receiving the funds instead my account that I requested long ago to be transferred to prepaid has not been changed since March this year instead they creating a bad profile for me and saying I'm in arrears not forgetting the complications they cause in my life when blocking my network.Im fed up please I need something to be done to maintain a healthy relationship with me as a client.<br> [Email Removed]
