- 500 download does not mean 500 purchases and does not mean flawless run
- it is not necessary open ticket on market, you can ask for help in any channel, only reason to write ticket is "that communication can be used in refund case", but I think on forums it is same, or more-less same
- "If any of the authors of the Market can not help you, the Osclass team will return money." - what author should help him? If you do not help him, you will be withdrawn and refund will be paid from your money, more you can be banned from market
- "In July I had a rest and sometimes answer in 2-3 days." - but you did replied on forums after more than one month ?
