MTN Kimberley not intrested in customer service

I have been a happy MTN customer for more than 12 years until today. I was called yesterday to pick up my new contract phone the main MTN branch in Kimberley. This after I waited more than 2 weeks for the upgrade to be processed. Am current on a anytime 350 that suits my requirements perfectly.I am and also a Anglo American preverential client.that I relized today means nothing. I was told that I can only be offered a anytime 200 as this is all I can afford!!!. And because of this also the close to R500 credit I have on the current 350 package. I am in a senior position in my company and can afford any package they have to offer. I have never been so insalted in my life. I asked to speak to the Manager and her attitude was simple take it or leave it. Although I get a a substantial discount as a Anglo customer at MTN I will be taking my small no meaning business elsewhere.
