WORST PRODUCT AND WORST SERVICE EVER

Worst decision I ever made moving my internet to RAIN. From the start I had almost no signal 1.6 - 4mbps. They called me, and told me to check other rooms in the house for better signal. Hassina said she will call me back in 10 minutes. I had to walk all over my house to check for better signal, which I didn't get anywhere. After a couple of messages from my side and an hour and a half later, Hassina finally called me back and said she will send a technician to check and if that doesn't work, they will put up an outside router with no additional charge. After 2 days of waiting, technicians finally showed up. Sat there for 5 minutes looking at the towers pinging. At this stage as anyone can imagine, I'm quite ****ed off. Now again after a lot of angry messages and 2 days later again, Hassina phones me and says that she got the technicians report that says there is no coverage and that I should downgrade to 4G. My question is that - how can there not be any 5G coverage, but when I search my address on the website, it clearly states that I have 5G coverage??? So Hassina's answer is that there are too many obstructions, and even the outside router wont work. Me: So, why wont it work? Hassina: The technician said so... He tested the device and it wont work. Me: The technician didn't test an outside device. He wasn't even outside. Hassina: No, but he is a trained professional and he assessed the area and noted that the outside device wont even work. Now another question to ponder: The nearest Rain tower is behind my house... The technician was only in the front of my house!! How the hell did he assess the scene to know that an outside router wont work??? Is the technician perhaps some kind of human signal detector that he could know that he wont get better signal at the back of my house? Or does he perhaps have x-ray eyes, that he could see through my walls and see all the obstructions at the back as well? In my opinion, the Rain staff is not competent to do their jobs properly, they cant give straight answers. It seems they don't know what the hell they are talking about.
