Dissapointed at Rain’s support services

Experiencing poor support from Rain the last few days. The sim cards recieved with the rianone contract worked fine until here mid desember. Having poor to no signal. On the 15th of Jan I logged the first call (***) stating that I've checked the apn settings and the one device have two sim cards. The one rain and the other cell c sim card. Swopping the two cards, the problem is the same. Then 48hours later I logged another ticket/call (***) reffering back to the origional call been logged (***) to please assist with the poor to no signal issue I'm experiencing. The I received a reply saying my Problem will be send to the right department. On the 22nd of January we received a e-mail to please check the apn settings and how to check and set it up, also to install raintalk on the device so you can make calls. Clearly they did not read the full fault description that there are “POOR TO NO” signal and I did checked the apn settings on the devices. Yes the one Phone I had to install Raintalk but the other Phone has VoLTE capabilities and it worked fine but we have no signal.... Today is the 27th of Jan and according to “my rain” app the one phone has 56m54s and the other 40m38s of airtime not being used. Now it is close to the end of the month, I’m losing all this airtime and pay for a service that does not work. I have been patience since the 15th. Is this how Rain treats their paying customers???
