Telkom *********** their own customers!

Telkom *********** their own customers! I received my bill (dated 1 September 2019) and in my detailed bill I saw that I was being billed for Telkom to Telkom calls 021 and 044 numbers (I have 3000 mins per month) + I was billed for SMS's (I have 50 free per day) - so i logged a call on 30 September @ 07h50. I received confirmation via email, but when I phoned Telkom (081 180) on 3 Oct they were unable to find my logged calls. I then provided them with a copy of my bill (via email) after being placed on hold for 28mins requesting them to provide me with an explanation and as requested NOBODY BOTHERED! I followed up via email again on Friday, 4 Oct but STILL NO RESPONSE. I've already received my October bill and the same issue with being billed for Telkom numbers. This is really bad customer service!
