horrible 5G speeds

Bought a 5G Rain service last week Tuesday I cannot use it because the is Speed is 0.05 mbps I also sent them the screenshots of speed tests . I logged two calls. one on Thursday last week and another one Monday this week. I followed Up each day but I keep hearing the will escalate to Networks dept. But nothing from networks. Hera are the two tickets *** and ***, ***. I followed this morning and I am told the matter will be escalated to networks. I am still sitting with the RAIN 4g which I wanted to cancel if 5G would work but it seems now I being double hit. If something does not work , just tell us but false advertising is a very bad thing. 5g Is supposed to give 30mbps output but I barely get 0.5mbps. I dont mind if interference drops me to 15mbps but 0.05 its a horrible figure. Lastly I got a from networks and we change a setting from SA+NSA to SA ONLY. it picked up 11mbps while the technician was online with me , I got ecxcited. but 10mins after henged up i got from 3mbps till 0.17 mbps again. I had enough of this . i just want my money back
