Pathetic service

Bought two Defy appliances and both appliances are faulty. Report it to customer services at hifi corp. i get told that they will exchange both appliances for new ones and they will fetch and deliver the appliances from my home by 16h30. 18h00 comes and i get a call saying they cant deliver the driver is stuck in traffic and they cant deliver next day as they do not have a driver then only the following day. So i asked the manager cant he work 30min extra to wait for driver and give customer service and my reply was a very calm no we dont. So now Mr manager i will be sending my laundry to the laundromat and YOU WILL be paying for it as i cant do washing now for 8days because you do not want to work 30min extra and only can exchange goods an extra 3days later. If this is hifi corps policy then i will never be buying goods from hifi corp again!!!! And i want my money back!!! It is sad for a manager to just accept just giving money back and not going out of his way to help a client and make surr they are happy! Thank you hifi corp for my laundry being washed on your account!!!!!
