Buyers do not have an automatic right to cancel a purchase
You can ask but the seller does not have to unless they are a business in the UK
Even then many will just send the item if you have paid
If you have and you want to return it then you open a return request and if the seller has REturns accepted on their listing then you can return at your own expense
If you have not paid then ebay will send reminders to pay and if you still dont then the transaction will be cancelled and you will get a non payment strike on your account
Buying and then wanting to cancel wrecks the sellers listing and costs them money
