Pathetic service

on Monday the 29th of February, my wife an I did an online grocery shopping and were advised we will receive our order on Thursday the 3rd of March between 14:00 and 15:00.the order number *** was provided. A follow up email and sms were send informing me that the order is on and I need to make sure that a signatory will be on the provided address to receive the parcel. I received another email informing me that parcel cannot be delivered due to some technical issues. I called your call centre and a lady by the name of Noluthando advised me that the order might be delivered the next day due to back log. When I called again I was told it might be due to payment issues. Payment method on your site is credit card only and your call centre advised me that a debit card will work.<br> why was I not informed earlier that this didn't work or my payment didn't go through. Online is a convenient way to shop but unfortunately this kind of service will make you lose a market share as customers don't matter to you.no effort was made to contact me and advise on what was going on and how to resolve this.please share this frustration of a client with the Chairman Mr Ackerman and CEO Mr R Brasher
