Pathetic customer service - ***

I recently bought a few items (7) on the New balance online site on the 15th of May. Payment went through and I received my order number and a week later my tracking number as they said they were extremely busy. On the 27 May I received my order from the courier. The packaging received was not sealed it was stuck down with thick clear tape which is unusual for Dawn Wing. I asked the driver before he left if i could open the package while he waited and he said he does not need to wait and i can contact New Balance if there is a problem. I opened the packaging and there was 2 items missing. I bought 3 sets , a shirt and cap for my kids. A cap and shirt was missing. I logged onto the site and complained, I also emailed them directly. I emailed a one pic s the other were too big. I received a ref number but no response to the problem. To date i have not received a call. This is very bad and pathetic customer service and it has put me into a huge inconvenience. Incomplete order #*** - ticket number for ***
