Rain 5G

I switched to the Rain 5g from a VDSL solution in January, a decision I have come to deeply regret. The internet access has been so inconsistent that it is unusable for work purposes. While I understand the lockdown has placed additional pressure on networks I am not even getting any feedback from my call tickets. My call ticket numbers are ***, *** and ***. The speed test performs really well for short periods but then stops working altogether. The web signal indicator varies from good to nothing with the router mounted on the same spot. I have been all over my house trying to get better service to no avail.
