Continuously being billed for service I cancelled

Hi,

I am being billed for the period of 12 August - 11 September 2017 for a service I requested to cancel on the 29 June 2017. The invoice number is 708C ********** B.

1 - On the 29th June 2017 @ 3:23 PM (Subject Heading: Consumer Request for Contract and Service Cancellation - IDNo_ ********** 230088 AccNo_ ********** 80143) - I completed/signed the cancellation form as required and forwarded it as well as a certified copy of my ID to ********** as well as **********

2 - On the 3rd of July @ 12:10 - I received the following sms message from Telkom (number +27 81 ********** ) - "Dear Valued Client, We are sadden to inform your cancellation could not be processed. Kindly contact your Provider to release your line to Telkom. Regards"

3 - On the 3rd of July @ 12:22 PM (Subject Heading: Re: Consumer Request for Contract and Service Cancellation - IDNo_ ********** 230088 AccNo_ ********** 80143) I resubmitted the completed/signed cancellation form as required as well as a certified copy of my ID to ********** as well as ********** after releasing the line as requested.

4 - On the 6th of July 2017 @ 09:05 AM - I received the following sms from Telkom (number: +27 81 ********** ) - "Dear valued customer herewith is the reference number related to your cancellation of ********** 543. Ref: ********** 95A .30 days? notice period applies TelkomSA"

5 - On the 16th of August 2017 at 1:10 AM - I received the Telkom Invoice email and need to pay for the services dating 12 August to 11 September (which is clearly over the mentioned 30 days that they alluded too.)

Please could someone with authority resolve this issue.

Unhappy Customer.
