Last minute Postponing of Delivery

I had a very bad experience with this delivery service. They have seemingly automated sms's notifying customers of deliveries. I had my delivery arranged for 5 December 2017, i received the sms saying they will deliver on the 5th December 2017 on the 4th December. I called the entire day to no avail on the 4th in order to confirm the time they will be able to deliver on the 5th December.

I then again called this morning, only to find that the delivery wont be made 5th December due to some backlog. I am very upset by this as i planned for the tv to be mounted and now this inconvenience is costing me to cancel my handy man to not mount today.

I am also extremely disappointed as I had to keep someone waiting for you to arrive today. How can you not advise customers that their deliveries wont be made on the scheduled days? Why do they have to contact you to follow up?

Very upset, Dolly
