wrong billing after upgrade

<p>After receiving a notification that i am due to upgrade, I went ahead with the upgrade and changed my contract to the plan 100 at the end of January 2016. i was told that at the end of February i would be pro ratad and must expect to pay a little more on my account which i agreed to. at the end of March Telkom deducted more than double the amount i agreed to on the contract, i contacted the service centre and spoke to them and a case was opened and i was told they will contact you shortly which never happened i was always contacting them with no resolved issues. when end of April rolled around what a suprise(not) Telkom again deducted more than double the agreed amount, I then notified them i was going to reverse both transactions and pay them what i agreed to pay them for the two months, which i did.(have proof of payment). as the month of May was going by telkom promptly cut my connection and suspended my contract due to non payment. Today the 21st of May 2016 i went to the telkom store in East Rand Mall to see if i could resolve this issue there as that is where i upgraded and was told they cant do anything to help me and must wait for the case to be attended to. so after all the frustrating calls to the service centre i still have no answers as to when and what is happening. very disappointing telkom mobile!!!</p>
