We are so sorry that you are having difficulty completing your payment. As extra payment security, we do require that you confirm your postcode/zipcode at checkout. The postcode will need to match to the address that your payment card is registered to, as if this information does not match, your payment may be blocked.
If your card is registered to a different address to your home address, such as a company card for example, please enter the postcode that your card is registered to, and this should allow you to complete your payment without any further hassle.
If you are based in a country that does not use postcode/zipcodes, then this entry box should automatically be removed from your checkout form.
If you do have any queries about payments, please get in touch with our team and we can certainly help!
