Dish Latino Dish Network Cancel account charges when I never cancel, fees not applicable, unable to correct there errors SAN DIEGO Nationwide

I am a client of Dish Network with a 2yr contract, I signed up for 9mos. suspention plan that they have paying only $5/month, it ended up the begining of feb 2015 and the account became active again, which I didn't became aware but when I did in April 2015, I pay the "chargers" we agreed when I called and after that I requested to disactivate(suspend) not cancel account and continue with the $5/month with no service again...

Anyways I received a bill again for montly charges, and than a box to return everything to them since they claimed that my account was cancelled for not paying for 1 month...

They refused to correct any error they made, and gave me 2 choices: 1. pay $1800+ or 2. pay $125 to reactivate account and than disactivate again for 3months....

I tried to avoid those changers since that was not what we had agreed on april when I paid the fees we agreed, but  they refused to corrected. I even told them that my sister was able to take my account and transfer to her and that she could stay with them so they won't have to lose $$ but still they want money I should not have to pay for their mistakes...They didn't care for What I had to say or my concerns, and now I'm concern about my credit, that they are going to report it when I pay what I had to and we agreed to something and they didn't honor that.. very bad customer service.
