Telkom Connectivity Sucks

I am on Telkom LTE Top-up and have been experiencing issues with the loss of connectivity since the very beginning. The week after month end i usually have no signal (2 or less bars on my wireless router). The has been going on since February but what has promted my complaint is that i am now going on 3 weeks without connectivity. I tried to call telkom, they told me to contact 081 180 as their technical line now only deals with ADSL and Fibre issues. I called the above-mentioned number and was given a WhatsApp number to do self-service with. That proved to be completely useless too. I have tried to change the location of the router in the house as well as any and all apn settings...nothing. instead my tether app tells me it cannot identify the sim. I buy a minimum of R1000 worth of data each month but being unable to use, while working from home is frustrating. No, i don't want to migrate to fibre. I just want someone from Telkom to contact me and help me resolve this connectivity problem as soon as possible.
