Rain One - Bad coverage & Incompetence staff

I opened a 'Rain One' account just a few days ago and have had various challenges ever since. The promotion comes with a router and 2 sim cards which are to be ported to Rain. I followed the steps however low and behold the x2 numbers were allocated incorrectly between 2 numbers! Furthermore one sim still states 'emergency calls only'. Had to call from a different device as both networks are non operational at this point. Tried calling the call centre number to escalate and spoke to 3 differnet support staff as the line kept 'dropping' or was 'delayed'. Last attempt I tried calling a supervisor but no-one was available. Eventually had to explain the fault again and the staff member was as surprised as I was and didnt know how to fix the fault so escalated it. So in the meantime my 70yr old mom who lives alone also has no network coverage due to this blunder and I have no idea when or how it will be fixed! Also regarding the router coverage, I explained that I am paying for this product however the router will be used in a different location to which I provided the address to confirm coverage. They explained there is no 5G coverage however there is sufficient 4G coverage for usage. I tested the router at that location yesterday and there is either no coverage or it intermittently spikes to a whopping speed of 2.27download and 2.21upload (which is totally unusable) for a few seconds then drops to no signal again. I moved the router throughout the premises to no avail.
