Lack in customer service

I've been calling Edgards Zevenwacht Mall for 3 days now, still no answer. I contacted Centre Management and asked for an alternative number and were given the same number that I've been calling since Tuesday Morning. Left my details with Centre Management on Tuesday & Wednesday in order for someone at Edgards to return my call, still no luck. At this point I am furious, livid at this service, or is it even service after all??? Surely someone can hear the phone ring... I had a repair that was booked in May and need to follow up as this is the second time the cellphone is going for repairs...but seeing that Edgars cannot answer or return calls, I wonder how long the repair would take. This fails to meet a clients expectations.
