Increase

I just received a mail saying that I will be getting an increase as of the 1 May 2015. <br> <br> 1. I just signed a 2 year contract August 2014. under a year and an increase affect a contract signed?<br> 2. when logging onto the website to check the T&c's the site is under maintenance (I smell a rat), is this to update your policies to say that you have the right to do so? its a binding contract as far as I see it.<br> <br> I have had it with Vodacom this is the final straw with you guys, I will not be renewing my contract in the future and I will not let my wife renew hers either and hers is up for renewal by the way! 12 years I've been with you and the past year I have logged so many calls because of issues I have had with you people. <br> <br> <br> I hope I am not the only one complaining cause this is totally unacceptable <br>
