Cannot make purchases due to captcha

Every time I get to checkout and select payment method, but before I can even pay, the page reloads and displays a captcha for "security". When I solve it, the page reloads with another captcha. This repeats endlessly.

 

This has been happening since April. I did a live chat who said they'd forward the issue to the technical team and that I could expect a resolution within the week. It has now been 1 and a half months.

 

I have tried different web browsers (Edge, Chrome, Firefox), including without any add-ons like ad blockers, and recently I happened to reinstall Windows. It is still happening.

 

I somehow managed to make one purchase in late April, but I cannot at all now.

 

Other individuals in the same house on the same connection have no issues with their accounts.

 

I would really like to actually be able to make purchases.

 

I cannot find any way to contact eBay about this. No option for technical support and no email address. And as I said, live chat did say they'd fix it but nothing has happened.
