I was trying to get some constellation coin for ethereum. I had a failed transaction. Customer service was fairly promp to respond. They asked me if I wanted a refund or to run the transaction at current market prices. I opted to run the transaction. I ended up getting 16500 dag coin when the current rate advertised was around 23500 dag for 2.037 ethereum I tried to bring it to the customer service persons attention along with a screenshot of the current market price. The difference cost me around half of an ethereum coinI got zero reply from the customer service representative.I’m sad because the service from them prior to this incident was excellent.
