Terrible customer service

So today we decided to place an order at the Swaadisht foods branch in Chatsworth, tried calling the number with no answer for over an hour, when we go online there's a whatsapp line available so we add those numbers and send a message on their profile picture there's a current special of a price drop, anyway we finally get them on the line only 2 be told that this special doesn't exist... mind u this was a really big order as we are a family of 20+ still the manager comes on the line and insists on the special not being in their store clearly management and staff don't know what's going on here on their own platforms. Please stop fooling your customers if you cannot deliver on your own specials.
