my friend, I was victimized just like you. the same situation happened to me 
((
I hope you didn't send them any funds, did you?((I think you can report to Namecheap about the site for being fraud, I dont know if they will take action but you should try. For the record, these are not scam accusations but just scam attempts on other sites using crypto as the payment method. 
Reporting to Namecheap seems like a waste of time, those guys are so slow on acting and without any evidence of one being scammed it even gets harder and within the next few days the scammer can easily come back with a dozen more scam domainsHere are the domains I and o_e_l_e_o got that are similar to Bitexnet
