No feedback on order

I placed an order with Builders on 10 July, the store selected indicated more than adequate stock and delivery was scheduled for 14 July. On 16 July I contacted the call centre to find out about my delivery and from there on it has been a frustrating process to get any feedback. Despite their call centre continously dropping calls, I managed to speak to at least 5 different consultants (online & telephonically) who all promised feedback including 2 that I spoke to today 20 July. One week later and nobody has returned my call to give me simple feedback on when my order will be delivered. I can't imagine how hard that must be! I keep getting the standard response, we apologise for the frustration yet nobody calls back with feedback.
