Bad service

Since the 25th of Feb 2015, i have been calling CellC to assist with the price increase that was done and not being notified about it as i was told the notification was done via sms and i didnt receive any notification, i requested for the contracts to be send to me or escalate a call back for the legal department but that was also not done...on the 7th of Mrach 2015 i spoke to christina from the sales department and i received a very very bad attitude from her(advising that am calling with a landline which i was not, just because i was transferred from a different department and on the system it showed the 084 number that i dont even know). this is very unacceptable
