Numerous Complaints and NO ACTION!!

Since the change-over from Nashua Mobile to MTN, I have had numerous issues with my account. I called the call centre multiple times without success. On 15/05 @ 9:10am I finally got through to Gordon & the following are ref numbers + issues which are still not resolved.<br> <br> *** (Refund)<br> MTN incorrectly loaded my data package details for the upgrade in Feb 15. I therefore incurred 'out of bundle' charges which must be credited. I was told that I would hear back within 7-10 work days. It is now >25 work days & no feedback.<br> <br> *** (Int. Roaming & Dialling)<br> I have always had Int. Roaming & Dialling active. After my change to MTN & upgrade, this facility was deactivated, even after numerous attempts to get it resolved. At one stage I could make Int. Calls, but when I was abroad (US in March), my Int. Roaming was inactive.<br> After my call 15/05 I received an SMS to confirm my Int. Roaming is now active, however now my Int. Dialling is deactivated?<br> <br> *** (Insurance)<br> My upgrade also meant a new handset. I sent a change of handset form twice, but still not feedback.<br> <br> *** (Customer Care)<br> I emailed Cust. Care 10/06 about the above items, but still no reply.
