No Connectivity and Cancelled Sim

I bought my 1st 4G Sim card on the 20th August and was delivered but the Sim was faulty and the 2nd Sim Card had to be ordered and do a Simswap. I started having connectivity issues and when I contacted Rain they tell me it shows that the Sim in near a tower close to where I stay and should be working fine, even after then al they could do was communicate via emails. I then decided maybe if I upgrade to a 5G it wouldn't be a problem and so I did. Package was deliver yesterday but the Router is not working as the signal and Network light bulb is Red even since it was delivered. The 4 G Sim was deactivated which means iam not able to use. How can they deactivate without confirming if the new 5G Package is up and running. I got a call from Gretchen Francis yesterday at 16:10, where I explained the situation and call disconnected while on the line, then he send an email that I disconnected the call where I was also surprised as call got call from this end and he never made the means to call me back. I responded back to his email and requested him to call me back which never did, logged another quiry but still no one called me. I took his Rain for work purposes and now am unable to work as I don't have connectivity solutions. Ever since if joined Rain all I've been trying is 1 problem after the other and all they do is communicate via email. How can you tell me that everything seems to be working fine on your side where else me as YOUR CLIENT am having difficulty to connect or the device is not working on my side.
