Poor customer service. Unacceptable packaging & care

I recently purchased 3 items from kiddiecare, 2 maxi cosi car seats and an isofix base. After a few days wait I received 2 packages. The isofix base and the larger of the car seats. The car seat had be shipped in a cardboard box which was at least 2 inches too small and held shut with one piece of tape. Needless to say, in transit the piece of tape buckled as the car seat was sticking out of the box at either side, I'm surprised it even arrived. Anyways so I was looking for the invoice to see what was sent and why I only had 2 out of 3 packages. There was no invoice, either that or it had fallen out of the box. I contacted kiddiecare who advised me they were a paperless company and do not send invoices. Which was fine, however an email would have been nice to tell me my items had been dispatched, and the last would arrive in due course. I also sent them pictures of the package as I could not believe they would send an item out with packaging in that condition. There response was that this was a courier issue. I'm pretty certain the courier wasn't the one who used a box that was too small!! I tried to tell them this but they didn't appear interested. So I wait for the next package thinking that it can't be any worse...the baby car seat arrives and low and behold it is worse! The box is all ripped, there is again one piece of tape attempting to hold the box together! I couldn't believe the state it arrived in. Again, I was angry and again I contacted kiddiecare. They unsurprisingly stated that it was a courier issue. And again I sent photographs and attempted to explain that this is impossible because quite clearly it is them who package the items and the courier is clearly only providing a delivery service. My comments fell on deaf ears. For a company supplying child safety products, they have no concern as how these items arrive to the customer. And despite numerous emails they will avoid accepting blame and ownership of their mistakes. Very disappointed and will not use again!
