DISGUSTING WAY TO TREAT A LOYAL CUSTOMER

I have been a loyal MTN customer for the last 15 odd years and even though their service has never been perfect, I have remained patient and continue to support them, until now. I decided to upgrade my contract online at the end of January. Received 1 email saying my request was being processed and that i could expect delivery within 10 days. I then received another email to say that something went wrong and i should contact customer care 083135 - so i tried and i tried and i tried somemore. 5 days later someone answered and said they could not see my request. They asked a whole string of questions and then proceeded to transfer my call to someone who could help - 3 transfers later still no luck. I then get told contact rewards company - Mohammed has captured the order and i will receive my phone within 7 days. 7 days later still no phone, no email, no sms. I call again. no answer. 2 days later i call and get a very rude woman tell me that mtn is having a problem with stock. WOW - this 2 days after i should have received my phone. MTN has all my details but clearly they cannot contact a paying customer to keep them abreast of their order. I have requested a call back from their service manager - NOTHING! Seriously MTN you have lost my business.
