Makro online site - Service sucks

I am an online business who deals with clients daily requesting options of how to purchase products whether in bulk or units, i use makro as for me it is easiest and quick to quote as it is online, try contacting the store via email its dealing with people who have the idea i don't need to reply, for me why does makro have an online site when they dnt reply about your questions to them. Their online site has more agents that resell their products but never at the correct price way higher, I sent an email yesterday one who is part of sales the other, which is the physical store, no replies from either. Makro please note service is what makes you a great store but your people that work for you need to understand the definition of sorting out someone's query when it gets sent. Your online site sucks big time and would have me looking elsewhere. The above is the 1st issue the second issue is i went into store to purchase pringles, i then realised they charged me incorrectly, sent the invoice to them the same day to correct, no response from anyone.
