Worst service ever Rain

Over 2 months of the worst experience ever. I've been with them for over a year so it is quite disappointing that now that I have a problem it cannot be fixed. 2 months ago my rain One router only connected 5G devices after they refreshed it. For 2 months I called daily until they decided to replace my router. 2 weeks ago they gave me a ZTE 5G router with the worst network ever. I've been calling daily only to be told that its been escalated and they have technical issues so they cannot see if my router is connected to a tower. Only 1 person was once able to connect me 2 a 5G tower but I lost connectivity again. I'm going into week 3 now with the worst network. I cannot work from home and they just keep telling me they escalating my matter.
