Terrible service and want to bill you for NO service!

Wow. So, in July my husband signed up for Rain internet, as I work from home and with loadshedding, he wanted me to be able to continue my job without needing to worry about Fiber at is always down... So, we received the router and sim, plugged it in and used it for just over a week until BOOM loadshedding hit, and guess what? Rain doesn't work when there is loadshedding (even though the router is plugged into a UPS - their towers go down)! Not only did my internet not work, but I lost out on income because I could not perform my duties! At the beginning of August, my husband cancelled rain, yet, here I sit with a router that has not been collected yet, and I am being BILLED R499 for something that has been sitting in a box since the first week of August!?! Highly disappointed! I had high hopes about this company, but not anymore! Rain - please sort this out in a timeously manner!
