Please waiver the content subs amount of R499.50

So I received an SMS notification from Telkom for the Month to Month agreement for the WIFI SIMS (***) - that I have with them for an agreed Monthly amount of R398.00. However, the SMS notification that I received today informed me that a debit order of R897.50 will be collected from my account on the agreed date.

Please note that the amount is more than double what the agreed amount is and I cannot afford this payment as I did not subscribe to the additional services that I am being billed for. With the sim cards being for providing a WIFI signal and inserted into a device you would think that the service provide would make a provision to block content subscriptions but not in this instance.

I would like to plea with Telkom to waiver the additional amount of R499.50 which I did not subscribe to and had no knowledged of this until I logged onto the portal via the work system and noticed and cancelled these subscription in Feb.

I have been a loyal customer of this network and even ported my Cell C number to Telkom.

All I am asking for is for future content subscription to be blocked on my account and for Telkom to waiver the additional R499.50 - which I am unable to afford.

Hoping for your favourable outcome.
