Wrong shipping address

I buy 1st time product from Pimoroni (Raspberry Pi 5 and all relevant products). When I entered the postcode in my shipping detail it gets automatically wrong house number in my address . but the street and Postcode are still correct. The delivery coming through Royal Mail. Is royal mail can contact me on the phone number.
because Pimoroni not responding to me by email. now today is 3rd day. I also have a lock ticket. but still no response.
Does anyone have Pimoroni’s contact number?
