No response from MTN in simple query

Please can I ask for assistance in the following matter.<br> <br> I have requested a settlement balance on the above number, which was the contract I signed up for while at Dimension Data.<br> <br> I have contacted the MTN support centre on 808/809 and requested for my contact details to be changed to [Email Removed] as I have not received my invoice since leaving Dimension Data.<br> <br> I have also requested for a settlement balance twice now, to be told that it will be sent to retentions who will sms the balance in two days. It has now been over a week.<br> <br> I then contacted 808 again today and had the call cut three times, then was put on indefinite hold. I then asked to speak to a manager only to be told that they cannot escalate to a manager as they are all in meetings and they cant transfer to a manager.<br> <br> I was then given a number for retentions and the head office, which are *** and *** respectively.<br> <br> Please can you assist me urgently with this issue.<br> <br> I have been given another cellular contract at my new company, which is the reason I am looking to pay out the contract. The company uses Telkom mobile for their provider.<br> <br> Thanks
