Extreme overdue late delivery

I placed and paid an order in full on 05 August 2015 with [URL Removed] on 12 August 2015 when I followed up on my delivery date I was informed that they have no record of my order and re-created my order. According to the website it takes 7-15 working days delivery, but no where it indicates that it might also be delayed and longer should customs keep the items back for a reason not allowed to be discussed with the customer. My order were received from the supplier at the *****hill warehouse but send to the wrong customer and the whole process of ordering from the supplier had to start over AGAIN, which means I start with a fresh 7-15 working days plus a possible delay from customs. I send emails, get no response, not even from the manager. I'm not allowed to contact the manager directly and when I call the landline on the website on a lucky shot I get someone who answer the phone. Got a late delivery refund of a certain percentage of my order and a gift to say sorry BUT here I am today 14 September 2015 a month later, still not received my order and after a phone conversation I can still not get a delivery date. Its the worst service I received from any online store in my life.
