Poor customer service incident

Ordered clothing online 2 weeks ago, due to be delivered last Friday 17th. Did not arrive. No call, no delivery, no note. 4 calls to Customer Service to follow up, all very disappointing: no one knew anything, they would get back to me, etc.

Today I again followed up, was told a manager would call within 30 min (that was at 11AM). Now after 7PM and still no call, no email, no response. No reply to mention on Twitter either. I am out R500+, with no recourse it seems.
