Won't acknowledge they are the problem

Our dealings with Coastal Kitchens has been nothing but a disaster and frustrating to say the least. We are based in Mozambique and did a full house order of built in cupboards and 2 vanities to be flat packed and sent on a truck which we arranged. The order arrived and only one built in cupboard out of the 5 ordered had all the parts. The floating vanities were missing the brackets and we were told to just make them up - not the point, we paid Coastal Kitchens for them! Keeping in mind that the shops are a 3 hour drive from our remote location. One cupboard had the wrong drawer sizes, missing shelves, missing drawers and an entire missing cupboard (ordered 2 of the same for the 2 spare bedrooms and only received one). Also no hanging rails. Requested the cutting lists - found numerous errors which Mary-ann acknowledged was her mistake on the phone. Sent them all the errors, they told us we are not going to argue with you and will resend - no apology all made out like they are doing us a favor yet we already proved they had made mistakes! Waited 3 months to receive the outstanding items only for them to arrive and still missing items and items we never even asked for! This has cost us transport twice, 17% VAT in Moz twice and we still now have to make up the missing items ourselves at extra cost and time. They just will not acknowledge their errors and keep blaming us and now possibly the transport companies which are two totally different companies yet Coastal Kitchens order is the only order with missing items. How does an entire cupboard disappear (which comes in a few different boxes) and no-one had the drawings but us and Coastal kitchens. Keep getting told that they "have never had issues with regards missing items". Owner has been in on all the e-mails but hasn't even bothered to try to get hold of us to sort it out. Wouldn't suggest anyone utilizes their unprofessional services.
