You're UK registered and there's nothing in your feedback to indicate any previous problem with deliveries.
Have you perhaps moved? I don't know how you think we can help if you don't wish to disclose where you live.
Are you sure the problem is delivery related? When a buyer finds that most sellers won't trade with them it's usually because they have received two or more unpaid item strikes for not paying.
Or could you be trying to buy items which have been recently prohibited from delivery, for example live fish or hatchng eggs?
More information would help. This isn't supposed to be a guessing game.
