Delivery messed up - Rubbish service

Delivery scheduled for 19 Jan for bed frame + mattress + cover. First the driver calls and says it was going to be early, then calls back and it's stuck in traffic! Then he realizes that only the frame is in VAN he decides not to come at all and reschedule. In the end I managed to convince to deliver the frame and re-arrange for the Mattress.
But re-arranging for the Mattress was not so easy. Several calls to deposit (tell you to call cust service), customer service (they tell you to call deposit or wait to be called) and the actual store (poor guys can't do anything from there). After a few days they called to re-arrange for the 10th FEB (20 days later my original delivery!!!!!!!!!!!!!!). It's a bed - you have to sleep on it!!!!!! (the store offered to lend us a mattress we did no accept/need).
Anyway on Feb 10th guess what? another missing item from the delivery: the bloody cover!!!!!
I did ask for a senior customer Service rep to call me and they are simply useless, as they just called me and explain what was going on, simply sorry. Oh but it did offer to send the cover to the nearest store (don't know when yet)!!!!!!!!!!
Now let me explain what you should have done with your customer: once you realise you messed up the mattress delivery you should have called your customer straightaway (proactively), apologise and organise a delivery by outsourcing it from a different delivery company, not wait 20 days for your own next delivery van route to save money!!!!!!!!!!!!!!
Never buy from you again!
