Rain is a ****

I have been going back and forth with rain for a month now,my issue started when I called the customer care line to cancel when I spoke to a guy by the name Lulama who promised to get my issue sorted and even came me a discount(which was all a lie) he later discovered that my current router was broken and had to be replaced that's when he transferred me to a lady by the name Patricia who was supposed to replaced my current router but instead issued me with a brand new subscription, fast forward to when I was supposed to pay I was told I owe them for 2 router my question to them was how am I supposed to pay for something that is not working.. it was their mistake not to cancel the broken router and now I'm being harrased by them telling me the are going to black list me.. I never said I don't want to pay. I just won't pay for something I didn't use.. If this is how you run your business them I'm not happy. You guys are bullies and ****mers
