DO NOT ATTEMPT TO USE RAIN NETWORK

I took a Rain router with 3 sim card on that R1 specials and the next month I couldn't continue with it and requested them to collect the router because I couldn't afford it. They collected it successfully and now they are busy harassing me that I owe them R557.90. I really need to know what it is for?

Stop taking chances on me because you cannot be connected without a pay and I don't know what are you charging me for
