****ty Services provided by Rain and their technicians

A few weeks ago I wrote a review about how Rain isn't taking my plea about changing my then router not serious and then they sent a technician by the name of Andrew to assist me with the Router issue and he changed the Router for the Huawei Rain 5G Router but again I've been experiencing problems with that Router the network is bull**** and I'm still spending a lot of money on mobile data all because I've been waiting for the so called technician named Andrew to come back and check what could be the problem and see if he can sort it out but Andrew has made me wait for his assistance for 3 whole weeks now and he still hasn't come yet. I try to communicate with him and try be understanding that he might be busy elsewhere bit my question is that, is plea for assistance not good enough for Rain and their technicians to be taken seriously whereas I make sure payment is received monthly by Rain but I have to put up with a ****ty Network from the Router and ****ty service from Rain and their employees. This is getting to an annoying point that I have to beg Rain for some kind of assistance whereas I'm paying monthly without fail.
