this company is a joke, FNB let down....

I ordered a new device on Friday 18/12/2015. These clowns contacted me for delivery details which I gave them. The call centre agent informs me that delivery will take place within 3-5 days. Expected date of delivery is 06/01/2016. ***??? Ok I know not everyone passed maths, but seriously? So after a long conversation working out dates, the latest would have been 28/12/2015, thr system still reflects 06/01/2016. I then ask to speak to a team leader. I was put through to Sam. Sam firstly, tells me that the agents read off a script and tgere is an error as the warehouse is closed, but he will check what can be done. No promises. I was asked to confirm the device selected, but could not as they gave me a product code. I had asked him to verify if it was the correct one. He said he was not sure but would get back to me. Tiday is mobday, Sam is still calling... I want to speak to Sams manager, the ring leader of this circus, but I am doing cart wheels trying to find out who the ring master is....
