No Refund/ No Communication/ No Service

I executed an early termination on my contract about a year ago. I then got a statement with a credit amount shown of just over R4000. At that time I started inquiring but did not get any response dialing the 808 Customer Care number. In May this year, I resorted to e-mail to raise my request. On the 19th of May Jawwaad Gierdien responded and said that they received a response from the Billing Department and all they needed was my bank statement in order for this credit to be reversed and paid out to me-I sent this through. The 10th of July I inquired again with no response from Jawwaad or any other representative until the 4th of August when I got a reply to say I should contact them. As I was out of the country I contacted them upon my return on the 3rd of December where the lady apologized and said they have not actioned the refund and that she will do it now (***). I just phoned again after no further comm and was told it is not a credit but Retention/Account Department not making the necessary Journal correction. I am in a Finance Dep and cannot believe this - Fin Year End? Seems like Financial Compliance is also an issue at MTN! Poor and pathetic from this provider!
