Pathetic service from dischem online

Dischem online is worst most pathetic customer service places and online order 29-01 put in specific notes for delivery but the delivery people did not receive that note there 1st attempt at delivering was on a Saturday at 16:30 pm my specific instructions where Mon to Friday between 8am and 4pm I called the store multiple times regarding the order they transfer me to dispensary then hold on then the call cuts off I spoke to someone to change my delivery address to a home address but still nothing came through this is my 1st time doing a dischem online order and the only reason was that close by stores didn't have what I needed for such a big franchise this is pathetic
