Makro - a fly-by-night ********* ?

Ordered and paid for (including delivery amount) a microwave online from Makro on 28 November - aside from conf of order (from a no-reply address - VERY conveniently) I have received no follow-up ... I was advised initially when ordering that delivery would take between 7 and 10 days ... Today is 11 December. Our company has closed and no delivery and no response to my FB messages and posts and I cannot get through - I just hold incessantly on the phone which has cost me quite a bit of airtime already. What are they thinking ! THIS IS COMPLETELY UNACCEPTABLE on EVERY level ! They have - essentially ****** my money - like a fly-by-night ********* !
