Terrible, Inconsistent Billing from Telkom

<p>I have had the telkom 20gig daytime and 20 gig night surfer data service with telkom for a year and a half...i have been paying 399 consistently the first half of last year.</p> <p>However recently the billing has gone to ****...it has hone from 399 to 407....when i query it they claim i activated the CLIP (Caller line identitiy package)....i advised them this is a modemn with a sim card but is not used for a cell number who activated it?</p> <p> </p> <p>They pass the buck claiming "its in your contract" but this morning....wow! They billed 899! Instead of 399....and when i call...they cannot explain it but rather claim its because i requested it from my contrac!!! What?!!....***** this im cancelling this i will reverse all your debit orders from now i dont give a **** if you black list me</p>
