Rain 4G wifi

For most of this month (September), my rain hasnt been connecting. It says "connected without internet. I called rain, twice I waited for ages before someone asissted me. The first agent told me that she rebooted on her side. It still never worked, I called again and of course I waited for ages again before someone took my call, so more airtime. When the second agent took my call, he told me that he was going to reboot which I explained had already been done. He told me to restart my my router take the Sim out and put it back in, which had all been done. He then suggested maybe a new router was needed. So we went about this way yet still "connected with internet". When I called again, I was told that this issue would be escalated. It took 1 week before a agent contacted me. She sent me an email with details to reset the router. When I got home to reset the router, everything was working. However after two days again "connected without wifi" Once again I have to call rain, a agent will tell then Tell me that they have rebooted on their side or escalated it which will most likely take another week before anyone reaches out to me. It's pathetic that I've paid up for this month yet have had little to no signal.
