Unannounced increase and bad customer service

So, I'm due for an upgrade, pick up a catalogue, go in store and sign up for a 24month, R229 a month Contract. I get deductions of R239, assured it would be R229 before I signed with the MTN assistant, I'm thinking it's going to revert to R229, it doesn't, in fact it goes up to R249! During this time, my data runs out extremely quickly and I get inundated with spam smses! I contact customer care, get replies a week later, not apologising, just stating a Price Increase (couldn't even be bothered with grammar). I've been with MTN for probably more than 10 years and this is my 2nd Contract. <br> <br> Obviously they are not interested in resolving my issue and by just sending me a link afterwards of the price increase, is not acceptable. Also, the scary part is that while I still have a way to go with my contract, this incident tells me that they can increase my tariff ANYTIME and as MANY times as they choose! As soon as I'm out, I'm leaving MTN and trying someone else out there and will be recommending EVERYONE I know to do the same!<br> <br> Feel betrayed and very disappointed that MTN can have several competitions and endor*****ts running at once and couldn't be bothered to reward customer loyalty.
