Indicator with error

 

I bought an indicator, after install don't sent any signal and also there are a error in the signals. I try to contact the seller but he does not answer. What I have to do?

 
There is no any options to refund in the Market rules in case you already activated your purchase.
Anyway, I collected something related from the rules (about when the buyer can contact with the service desk, and so on) on post
