Good Ordering process, Poor Delivery service

Great Service. I ordered base and mattresses online a week ago, i was a bit disappointed when i got a call the following day that they do not have stock and will keep in touch with regards to the process of getting stock from the manufacturer and deliver. I was kept in the loop and about a week later i got a call for delivery the following day. I was happy. The only issue i have is with the delivery service. I sent an email the morning of the delivery asking to be notified about 30 minutes before they will arrive at my house because for obvious reasons one cannot sit the whole day at home "waiting for a delivery". Not in 2021. The delivery guys called me when they were at the gate around 16:30. At that moment i was on my way to pick-up the kids from school. I told them i am about 10 to 15 minutes away and will be there shortly. 5 minutes later they send an SMS that they are on time and cannot just sit there waiting. I told them you were supposed to call me before so that i can stay and wait and if you cannot wait you can leave. They tried to force the issue of leaving the beds with my very rude neighbour that does not even greet me. I said no you will have to wait. In the meantime traffic was 3 times worse that day. I told them to leave and they will deliver the following day... They said they will either be in trouble or i will be charged for another delivery. The guys did wait for me to get there. I really do not blame them. They told me they call when leaving the previous delivery address which happened to be only a kilometre away from my house. I asked them what time did you leave the warehouse and they said 14:45. So to The Mattress Warehouse, it would have been great if I was called at 14:45 when the guys were leaving the warehouse to avoid frustrations.
