NO STOCK WHEN USING ASAP YET AGAIN!!!!!!

What is going on in your stores. Whenever I order using your ASAP service there is no stock. The store that is picking my order is Norwood, the biggest store in Johannesburg. Whenever I do my shopping there there is always chicken breasts and a lot but when I use Asap amazingly there is no stock. This is now 3 times in one week. Also Asap taking over 24 hours to respond is not acceptable. Please deal with this.
