Billing just getting hiked

Deat Telkom <br> <br> I had the following issue which I am not very happy about. My bill has been hiked from R267 to R884 and every month I have to phone for my credit this is *******. According to the terms of my contract when my 24 months is up its supposed to goto a month to month. Further to that if you intend in hiking my price surely its good business practice to inform the person 30 days in advance. I am not prepared the R884 and if you not willing to hounour my current deal I cancling my contract now and since you have not provided me with a hike of service price I refuse to pay the R884 in cancelation period I will pay the R267. So please I happy with the network quality and would like to remain your customer but if you dont want me please follow good business practice and send me notice in writing<br> As per our telephonic conversation, please see below your case numbers.<br> <br> <br> <br> Case ***7 was logged today.<br> <br> Case ***3 was logged the 11/06/2015<br> <br> Case ***0 was logged the 14/06/2015<br> <br> Case ***1 was logged on the 08/07/2015
