Cannot get through to anyone!!!!!

Here I go again.... I have been trying unsuccessfully now for FOUR weeks to get a hold of MTN via the 808 Call Centre, Twitter, Emails and even the store (x2) . 1st, was me trying to get a hold to cancel my dad's 3G contract (unsuccesful STILL) and now I seem to be experiencing issues: In the last 2 days, part of my airtime disapears (Top Up Contract) . I am a previous Nashua Mobile customer and never had issues with them, however, since the change the quality in service with MTN has steadily declined.<br> <br> The 808 rings and then simply cuts you off. The staff in the stores arealso so busy due to the high amount of complaints.<br> Today, after waiting almost an hour in one of your stores, the lady assisting me managed to get a hold of someone at your call centre. Sadly, this only frustrated me more with the individual's lack of knowledge around the product/s and inadequate response to a possible resolution. Your staff really need to be trained on what CUSTOMER SERVICE entails... Since the change from Nashua Mobile to MTN , the service has steadily declined.<br> <br> I am out of contract and ready to port my number to a new provider....
