Shocking after sales service

I have had my phone with me constantly and there are no missed calls, so I find it interesting that no one can get hold of me - very convenient excuse. Someone did call me from the store and then they told me to call the technician. So much for customer service, now the customer has to chase after everyone. The technician did finally come this afternoon, after I called him, and told me the fridge has no gas (this is a brand new fridge!) and that it would need to be replaced. So I continue to sit with no fridge. And now the question is - how long is it going to take for a new one to be delivered?? I have still not received a call from a Senior Manager, and clearly no one is on top of my query rushing to assist me. I would like a call today so that specific arrangements can be made for the delivery of a new fridge. Thank you, Nicole
