Rain rude customer support agents

I’ve had a rain wifi for about 3years now recently my network has not been working well for over a month. Do I decided to cancel my subscription because I am moving houses so thought this would be the best time , in doing this process said cancellation would only happen once router was collected. Because I was confused why I was still billed but the network has completely been switched off I called into support to help. The rudest consultant answered and I’m actually shocked that this person would be so rude to a customer unprovoked. She asked me why I didn’t call in and ask why I only got charged half when I upgraded my subscription and was extremely rude and condescending. I am actually shocked that I called in to try deactivate my account but instead was met with such unprofessionalsm.
