Rain interner service is the worst ever!

I have had the absolute worst experience with Rain customer care. Since Saturday my internet has been down. I am an online tutor and I need my internet... it is hiw I live in these tough times, one has to do what one has to do! On Saturday I sent probably 35 emails to request assistance. I recieved 2 back saying they rebooted my modem and it will work now. Come Sunday - I can't teach because it is STILL not working. Then they I start again with sending the emails... I sent 14 and got 2 back... one said they are working on the tower and the other said they rebooted it and it would work now. IT NEVER WORKED. Come Monday, I send around 14 emails... SOMEONE finally responds saying that the tower is faulty and I must wait for 24-48 hours to report a fault. I then got adviced to upgrads to 5G. I changed the drop off point for 5G modem on Saturday already but it wasn't changed and was delivered to the wrong address yesterday. I contacted RAM and they could fix it, NOT RAIN! Now I charged my modem for the 3 hours but it is not working... there is no 5G SIM (that was rica'd supposedly) in the modem. I am loosing money... since Saturday I have lost R1000 with not being able to teach. I have sent 15 emails tonight from 19h30 'till present AND I HAVE NOT YET RECEIVED ONE EMAIL BACK FOR ANY ASSISTANCE. it is absolutely a nightmare. And there is no number to contact so you never speak to a person. I begged, I pleaded, I even threatened... I would like a call from anybody at Rain to help me BUT TILL THIS POINT NOTHING HAS HAPPENED. I would like some form of apology and even some form of insurance that this 5G SIM card will be in my hands before 14h00 tomorrow or I will be taking this further. I can't believe the absolite disgusting way they treat me... and I have been loyal! I wonder what would happen if I don't pay? They will cut it. BUT the one time I am blowing up their system NOBODY is even assisting me. I counted, from Saturday untill present, I sent out 58 emails to them and maybe got back 6 if I am lucky with no real help or support! I am DONE playing Misses Nice guy! Fix this RAIN, or you will loose a customer soon! VERY SOON!
