Woolworths online and call centre experience

I attempted to place an order online for delivery to a business team in Sandton. The website was highly inefficient, with my order having to be placed 3 times over before it saved, I have used the site many times previously with better results. I selected the option for no substitutions to be made. Substitutions disappointingly were made. The order that was eventually delivered was for someone else, and I only realized so when the recipient thanked me for the flowers which was not part of the order. On contacting the call centre, I made 3 attempts each time when asking to speak to a supervisor the call was dropped. I eventually explained the situation and asked for a supervisor to call me as this incident was highly embarrassing - being a corporate YE gift. I am still waiting for someone to call me from 3pm yesterday!
