Recurrent issues. Poor service delivery. *********** Technician

The service I've been receiving from Telkom lately has been pathetic. Firstly my ADSL line is extremely slow, I then logged a fault a technician named Gloria who was unprofessional and didn't seem like she know what she was doing she came to inspect the line and advised that she cannon assist as its not a telkom modem and question who my ISP was. Telkom has been my ISP for the past 3 years surely this should reflect on your systems. she then advises that she will inspect the line further and to date I'm still waiting for a response, another fault has been logged as my internet is still down.

There is another issue been having is the billing my payment made on the 22 March is missing please investigate as the invoice for March is INCORRECT. the service is just really disappointing your app is always giving errors, when contating the call center you wait forever more than 30min and still no assistance as the call was dropped.

Please resolved these 2 issues as soon as possible as Im quite frustrated at the poor delivery of service.
