We will accept all major credit cards. Some items may take longer to deliver however this will be communicated to you at the point of ordering. We try and inform you for the courier used on the listing page. NON-EU DELIVERIES For customers in non-EU countries, we find it is quicker and cheaper to actually send out our products direct from our manufacturing factory in CPR. If you are unhappy with this, then you will need to let us know at the point of order but as it is cheaper and quicker, we doubt there will be an issue as we are well versed in export. Some items are only in our UK warehouse, so will have to be dispatched from there. Whether your item has developed a fault, is damaged or is no longer required, we can help you out. This can be the sales receipt, a bank statement or an online sales invoice. They must include all original packaging, be in “as new” condition and must not have been used, installed or had any data input on them. We do not cover faults caused by accident, neglect, misuse or normal wear and tear. We are experts in what we sell, so don’t always assume something is faulty because it may well not be. Tell us your issue and we will know if it is or if it is not. We are here to help. DAMAGED PRODUCTS If you unpack your product and find it damaged, please let us know as soon as possible and please validate the claim of damage by supplying a picture of both the damaged contents and the parcel box it arrived in. We will assess the claim and resolve promptly. Only once the order has been confirmed as cancelled by a member of our team is this the case. We do not take financial responsibility for the cost of the return of any products ordered in error or that are no longer wanted. We will then arrange for your item to be repaired or replaced with a new product or provide details of the manufacturers local service centre. We are not responsible for installation costs under any circumstance. We strongly advise you to take care when returning items to us; for example, by ensuring the goods are correctly addressed & adequately packaged. Items that arrive back damaged or destroyed as a result of poor packaging will not be accepted. These items will be resent to the customer at the customer’s expense. If you have received a faulty or incorrect item: You must notify us within 10 days of receipt, we will then arrange to replace or repair the unit. This guarantee does not cover effects arising from accidental damage or misuse of the items, and is automatically lost if the item is opened by non-qualified or unauthorised people. Please note that minor issues may be resolved by supplying replacement parts or alternative solutions acceptable to both parties.
