Billing incorrect

I'm showing this as a compliment rather than a complaint because so far the service received from telkom was good despite the errors I've encountered.<br> The technician came to install my line on 23 July but did not have a modem in stock. I explained that I would not be available for the next week and will only be back on 31 July. He subsequently called Telkom to inform them that this is the case. However, I received a message stating that Telkom tried to contact me and that the message is confirmation that I will be billed wef 25 July. I tried calling Mirriam (who sent me the message) on *** a few times but received no answer. <br> <br> THIS IS A REQUEST to please reverse any charges from 25 to 31 July. The service was only active from 1 August. <br> Thank you
