Telkom doing **** to clients

<p>I have a contract with Telkom ( Acc: ********** 58 ) and I normally pay R140.88 per month. For some weird unexmpained reason it has risen up to R640.88 which is a total rip-off, midly put its **********. I will dispute this payment till they sort it out, worse no one has assisted on my prior request to upgrade ( I get a mere 500MB for R140.88 and all of a sudden I neeed to pay R640.88 ) Ridiculous!</p>
