Custom Charges on a parcel that I own

I have recived a letter about Customs charges I need to pay for a parcel.
However the item (a suit) contained in the parcel is my own, I bought it here in the UK, while travling I left it in my home country of Bulgaria.
I needed it now, so I had a familly member send it over, but I have been hit with almost 70 pounds of Customs charges.
Is there any way I can dispute those/recive my parcel without paying?

Hi
If you previously had the goods here in the UK then you should request returned goods relief .
You may need to provide some evidence that the goods were purchased in the UK.
All goods are potentially subject to import taxes whether they are personal goods or not. https://www.gov.uk/goods-sent-from-abroad/tax-and-duty
If you have paid then you can reclaim overpaid taxes https://www.gov.uk/guidance/how-to-apply-for-a-repayment-of-import-duty-and-vat-if-youve-overpaid-c285

Hi mitkoasd
Anything posted or couriered to you from another country goes through customs to check it is not banned or restricted and you pay the right tax and ‘duty’ on it. 
You can claim a relief to pay less or no customs duty and VAT if you re-import goods to the UK but this needs to be done when customs declarations are made.
You would usually ask the sender to write ‘Returned goods — relief claimed’ clearly on the package and its accompanying import declaration. 
The declaration must include a complete and accurate description of the goods, including their quantity and value. 
If you’re registered for VAT, make sure your VAT number is quoted on the declaration (CN 22 or CN23).
You can claim for repayment if you’ve overpaid import duty and VAT.

Thank you.
