Fiber promotion incorrectly invoiced - Struggling for assistance from Billing department

Good morning,

I am really not happy about the service that I am receiving from the billing department On the 09th June 2020, I phoned Telkom and inquired about the Fiber packages. The lady assisted me with the required information, but could not processed the request because of the system not operating that morning. She said that I need to phone back but need to ask for the Unlimited 20Mbps promotion package for R699.99. I phoned the morning of the 10th June 2020 and Angel processed my request. She confirmed that I will not be paying for the 1st 3 months as this was a promotion. Angel processed the Fiber as a new Package as I need to keep my land line number. She took my banking details and said that the payment will be a debit order. The morning of the 11th June 2020 I phoned again and just clarified that I will not be paying for the 1st 3 months and Kristen confirmed again. I received my invoice from Telkom on the 05th July and they combined both packages. Telkom invoiced me for the Fiber line (ZAR 999.00) instead of ZAR 699.00 (which should only be invoiced from end of September 2020. I phoned Telkom on the 09th July 2020 and they escalated the requested as this was a dispute. I phoned again on the 14th and 20th July and yesterday (21st July 2020) I received an email confirming that my call request was closed and that I need to rate the service. I requested for 2 separate statements and still awaiting, not sure why the call was closed as I am still awaiting feedback from Telkom. The land line was in credit beginning of June and now it is reflecting a debit amount for end of July. Telkom should not be advertising promotions if they not going to invoice the customer for the same amount

The installation of the Fiber was done 2 days after my request was processed (I was very happy and satisfied), but now I need to struggle to get my account sorted
