Yet another disappointment

I made a call from my prepaid number , I held on for 1h8min 47 sec, without assistance, clearly MTN doesn't not value its customers, not one keeps you updated on matters that have been logged, promises made by your staff never materialise.<br> <br> I have two complaints.<br> 1.One device has not been collected for repairs. Please confirm as when collection will be done along with a loan phone.<br> 2.One device still needs to be delivered as the device was still under warranty as per confirmation from by HVRC(Repairs) Helpdesk Technical Call Centre : ***,<br> <br> When are the below matters going to be resolved?!<br>
