MTN is a waste of time!!

I have not been able to use my phone for the past two days thanks to the brilliant service by my network operator, MTN!!! Everything from my BBM, Whatsapp, email etc has been totally inaccessible!!! I had a considerable balance of airtime on my phone, as well as a data bundle & sums bundle, however, the balance on all of these now suddenly reflects as zero & no matter how many times I recharge the funds are not credited to my phone. Then I get this constant message that I need to sign into the MTN network, but when I try to I get another message telling me that I need to recharge my airtime.....BUT I CANNOT, DESPITE ALL EFFORTS!! After 2 days I have no phone!! I am completely without this vital means of communication which I also rely on to conduct business. Then the MTN website gives you specific numbers to call for customer care, but not surprisingly, NONE IF THESE WORK!!! The number rings until it cuts off!!! Which means I have no assistance with this issues& I'm stuck with it. I must also mention that this isn't the first time that I have had this problem. It happened twice before & I'm quite tired of it!!! I NEED ANSWERS!!!
