cannot access Voicemessages (MTN ***)

we have a MTN - Bussiness account Fruit & Veg City. We had this contract with Nashua Mobile and all the MTN numbers obviously went over to MTN after Nashua Mobile closed. All the contact details were given to MTN, re: sending of statements, etc. We still dont receive any statements from MTN, AFTER 3 MONTHS!!!!. (complaint 1)<br> Complaint 2: My boss' contract with Nashua mobile also went over to MTN on the same business acc. ***) - From 2 days ago he cannot access his voice messages. Yesterday, I logged a call to your call centre no ***, after holding for 30 minutes. The lady helped me promptly and she said the MTN technical team have been notified and this problem will be sorted out within the next 24 hours. the reference number for this call she gave me was: ***. Although the 24 hours arent over yet, my boss STILL cannot access his voice messages. Ive been trying to contact *** again, yet nobody answers and I am holding for 40 min now. Can someone PLEASE help me on the above 2 complaints??? I cannot believe that such a HUGE corporation such as MTN can give such **** service.<br> Anel Theron
