Total Disappointment with Vodacom

I order a laptop with an upgrade and was told that the laptop would be there by Friday 7th June 2019. No phone call was received on the Friday to collect. We then called on Saturday for them to say that they are not sure and the person dealiing with the order was off for the weekend. I have left 2 messages this morning and after the 3rd phone call was told that the laptop was on back order and they can only tell me tomorrow what was going on. I find this totally unacceptable as this should have been told to me from the beginning or when they first found out that there was going to be a delay. My entire business is on a laptop and as such I have been without a laptop or any functionality for 2 weeks. This is one of the worst services I have received in a long time and I am totally disappointed in the service from Vodacom as a whole. I hope that this will be taken seriously as this is unacceptable service!!!!!!
