Business Wifi Technical Fault

I logged a call with Telkom on Monday the 23rd of October because my internet was not working with my ADSL Wifi. I was informed that a Technician will be in touch to help with my problem. To date I have not been contacted by a Technician. I called this morning again Wednesday 25th of October to enquire about the call I logged. I was again informed that a Technician will be in touch, we are now at close of business and no Technician has contacted me. Having internet for my business is critical, I cant receive and/or send emails, my business is pretty much on hold at this point. How long does it take to resolve an issue of this magnitude, surely not this long. My call log reference is 717CRK231017 and my business name is AC Consulting. My name is Andile Shabalala.
