Frustrated unsatisfied customer

I am beyond disappointed with this company, we have been using rain for almost 5years now and this have been great until a week ago, now rain is showing their true colours. You can call as many times as you like no one will call you back or give feedback, their supervisors are never available, I don't know how many times we had to move this thing around the house and nothing mind you we don't live in a mansion, me and my husband often work from home on weekends and we haven't been able to and the kids are still on holiday with everything smart TV, cellphones depending on a WiFi that we nicely pay monthly without fail not working. The cherry on top is rain will block your SIM without letting you know should you remove the SIM card from the device. I've just about had enough of them honestly, I can't help but think how Vuma will eventually take over because of rains greed.
