I couldn't log into the account I recently created...

I couldn't log into the account I recently created, reset the password, but the temporary password didn't work. I contacted the customer service by live chat and was told by the rep Sullivan that my first order was cancelled because it's not available and therefore my account was deleted as well. I need to create another account and place a new order. I has many online accounts for online shopping and it is the first time I heard that the account was deleted since the first order couldn't be fulfilled. It doesn't make any sense! How can new customer check the status of the order if the account is deleted? No email notification about the order cancellation or account deletion. When I requested for the confirmation for cancellation by email, the rep said they just confirmed to me. First and last experience with this company!
