Shocking Makro Online Client Service

I ordered something online from Makro Montague Gardens in Cape Town on 26 November and their site advises 7 tp 10 days for collection. I heard nothing and followed up TWICE by clicking the Contact button on their site and requesting feedback. I received no response to my requests. I then contacted their Call Centre and spoke to Ayanda and she was supposed to get back to me but failed to do so. I then mailed them again today and still no response to my mail. This will be my last Online shopping experience with them if that is how they treat their customers
