Problem returning item to seller.

I purchased an interactive toy from an online company in Sept that ceased working in 6 weeks. Although I used my everyday email address, paid for the item by debit card and supplied a name and postal address and have a bunch of backward and forward emails, I cannot remember my ebay user name ID which the seller is insistent on.  They have all my details and a record of the sale but are being less than helpful in assisting me with a return or repair because they say, I cannot remember my username ID. Is this usual or are they trying to 'bat' me?

If you do not remember the user ID for the account which you purchased under, may I ask why you don't sign into it with your email address?

 

Then, once logged in, hover over the G'day (your name) at the top and under that it will show the username for that account

 

If the company have a record of the sale, they would already have your ID you bought with

 

It sounds like they are playing silly buggers
