Shocking service from Makro Business Online

This is my second review about the same issue. We returned two food warmers to Makro Business, they collected both but only refunded one. This happened on 17 March. I have phoned multiple times, emailed multiple times, yet the issue does not get resolved. The previous review here got a response with a phone call 8am on a Sunday morning, but nothing further. Lets see if something happens now.
