Rain WiFi and they’re poor customer services skills

I took the Rain WiFi in April and was given a free month , while signing up I was never advised that it is a subscription and I am bound to make payments monthly regardless of the WiFi being on or not . I didn’t pay in may because of financial constraints thinking that it operates like any other WiFi only to find out after making a payment in late May that I also have to make a payment for June , I called twice to the cancellation department spoke to two reps Tania and Thando which were very rude to me and tania even hung up the call while I was talking to her explaining why I do not want to pay that money because I was never told that it’s a subscription
