808 NUMBER NO RESPONSE???

I have been trying to get through to mtn customer services after upgrading my contract and it is virtually impossible - I challenged the store in gateway in my presence to get hold of mtn customer services on 808 and they also failed. The same message repeatedly plays - We are experiencing high call volume ... for the past 2 weeks i have been hearing that - Why dont you employ more people if you are experiencing high call volumes? <br> I have been battling to set my call limits on my data package and my airtime packageand after the store set it i received another sms saying that it had changed - I had to call the store and ask them to reset it again - I am not sure whether this has been done or not. I had incurred high data costs Last month and could not get any help from mtn as to why? the store says that i need to contact 808. <br> previously caller id was st from the phone, now you have to call the operator to set this - Why? Cant we leave things simple instead of complicating it especially since there is no answer from customer services.<br> I was also not credited with my sms and data for the month of July - I called the store last week - Still nothing?? fed up now!!!
