22 years of being a good customer means nothing

I have been a good customer of Vodacom for 22 years. November and December 2014 I had a couple of issues and couldn't make payment, the account was rectified and brought up to date before the end Of Jan 2015. Now Vodacom has put a credit limit on my account which is now having affect on my income because my phone gets cut off half way through the month, I have consulted lawyers and am considering suing for loss of income. on top of this I cannot upgrade to a new phone because of limits put on my account by Vodacom. Being a good customer of 22 years means nothing to Vodacom, all they care about is getting their money in and they care nothing for their customers. THIS IS PATHETIC AND THE WORST CUSTOMER RETENTION AND SERVICE I HAVE EVER EXPERIENCED!!! the call centre now tells me I have to go to a Vodacom shop and stand there for 3 or 4 hours while Vodacom's useless customer service will attempt to resolve my issue! PATHETIC PATHETIC PATHETIC!!! CellC seems a much better option at the moment, even **** MTN would be better!
