Can't Expect to Contact Each Client

On Tuesday 4 August 2015 we drove from Bloubergstrand to Sasol Melkbosstrand as to purchase gas.We were advised that there is currently a gas shortage but that they were expecting a delivery later that day.We requested contact details and were given a business card of a certain Annelize Jonker.On Wednesday I send an email enquiring whether they did receive a delivery of gas.As I did not receive an answer,I followed it up on Thursday and send an SMS to the cell number as per the business card details.Still no reply.I then sent an email to Jody, but did not receive any answer.On Friday we drove to Sasol again to enquire for gas and learnt that the said Annelize was no longer employed at Sasol.We enquired why they did not respond to our emails and SMS and two young girls advised that we cant expect them to advise all their clients when they receive gas.Clearly they don't know anything about business or franchising, nor how to communicate with all their clients via an email data base.
