Vodacom does it again : *****s up

Its going into the fourth year having a contract with Vodacom and I simply cannot wait to cancel it next year .<br> Never in the past 3 years did my contract ever increase randomly in the middle of the 24 months.<br> Yesterday I received a sms to state my contract has increased.. what ******** is this? <br> This was never explained in the upgrade call or anywhere NEITHER is this normal practice!<br> And Vodacom.. lets not forget who is in possession of the upgrade call. So do not lie to me, also do not call me.. Since you can sms price increases, I would prefer you email me.
