Vox Non Service

On the 16th of July 2018, I enquired about porting my Telkom landline number to a Vox SIP account. On the 17th of July 2018 I sent off the required forms to apply for the number port. When I checked back with Vox on the 26th July 2018, the port had still not been completed. Only by 31st July 2018 I received an email stating that the port had been completed. After testing the number I realized that it was still ringing on the Telkom landline phone which I reported to Vox on 2nd of August 2018. On the 10th of August 2018 I sent an email asking when it will be sorted out and if they were not able to resolve the issue, I requested to cancel the port along with the Vox SIP account with a credit to my account. I eventually got hold of the "Account Executive" who I initially spoke with. He escalated the matter to the Port Support team on the 16th of August 2018. I am still waiting for a response from Vox. I sent 2 more emails on 23rd and 24th (yesterday and today) and made a call to the sales department were the sales rep did not want to put me through to his manager and rather transferred me to the "Account Executive" who I initially spoke with at the beginning of this painful journey. I held on for 20 minutes to speak to that person and eventually ended the call. I am still without a complete service. Vox can you please just cancel the Port and SIP account as I have asked you in the emails, and credit me for all cost involved.
