Call Centre really pathetic

From last week my husband and I have been calling into MTN call centre and the minimum holding time is 35 minutes , whats worst their call centre agents picks up & if its difficult or they feel they dont want work they drop the phone. Really MTn no consequences to your staff so that is why they do that, surely you should be monitoring them on the calls they take?!!! My problem was that my data on our contract was not loaded on time only my sms and airtime.***<br> Regards,<br> Laurell
