My biggest regret

I regret the day I decided to switch my WIFI from Rain to MTN. This was the biggest mistake I have ever made. I am now stuck with a contract for 3 years that is useless to me and costs even more. The network is bad, the billing is even more horrible, the router in noisy and never seems to work or connect. I pay more and more every month. What makes things worse is that the second contract they sold me was a total lie. Everything that was promised was not true. I need someone to help me please
