Canceled 4G only to have 5G connectivity taken as well.

I've been having a 4G sim for my phone (I have a dual sim phone) and 5G for my home. I canceled the 4G because I got a phone with only 1 sim, that means I can only receive calls on this new phone and no longer have a data sim. Rain went and took my 5G home connectivity IMMEDIATELY after I canceled the 4G. I can't use the TV, I can't do work at home, I'm literally internet-less yet you will deduct money from me on the first. I don't know if you're being spiteful or trying to make me regret canceling the 4G but overall I regret choosing this service provider who does not even pick up calls. Terrible terrible customer service.
