Billing and Service divisions to align to fully cancel service

I cancelled my service with Telkom on 12 May 2018 and was given reference ********** 21A. The service was suspended immediately. On 18th May - I received an invoice for services from 15th May to 14th June 2018 (post suspension date). I logged into their website and logged an email complaint, which i received a copy of a few day's later. I have had no response to my email and today, received another account for period 15th June to 14th July 2018.

Initially, I wanted my line re-activated but won't be proceeding with this request and have opted for an LTE router instead, where I control my spend as Telkom cannot be trusted with this.

Kindly send me confirmation that your service division has aligned with your billing division to resolve this matter.

I await your response.
