Rain

I had had Rain for the past 11 months for a business that i manage. From day one the network has been extremely unreliable, the speed drops to about 1.1mb/s and for the type of speed they were promising lets just say this is very unsatisfactory. Now i have come to a point of getting a new wifi producer and i have to cancel my rain. I have sent them countless emails on the fact that i would like to cancel my subscription to them with no one ever getting back to me, i have tried to phone them on multiple occasions yet the number listed on their website is not a working number. I have checked on their website to see if i could possibly cancel my subscription on there yet seems like that is not an option, i have no idea what i can do about this anymore, very unsatisfied about the level of service that i have received from rain. Any advice will be greatly appreciated.
