Rain

I have been with rain for over 2 years, and I regret it, I have been trying to cancel with them but out of nowhere I am in arrears, they keep sending messages about this issue and I am not going to pay , it was month to month and I have all the right to end it, I have sent several dm's on Facebook but still, the network hardly works , even their sim cards never worked, I hope they fix their issue and stop nagging us with non stop smses
