Bad Customer Service and Bad Treatment from agents as well as bad delivery services

i received an sms this morning stating that my order is out for delivery and it will be delivered before 6pm today. I then received an sms again at 15.13 stating that my order is next for delivery, shortly after that again at 15.13 i received another sms stating that my order failed to be delivered. I have been sitting at home the whole day as i had to re arrange my day so that i can receive my order, when i call the call centre i get bad service from call centre staff and they hang up on me. This happened 3 times, where agents would hang up on me. This is really disappointing as i have never ever missed a payment. Why are we being treated this way. The other disappointing thing is being told by the agent that i must wait 7 to 14 days and i when i told her about the messages that i received, she hung up on me. Another agent just asked me if i'm still interested in the order, i really don't understand especially because i was calling to find out why my order had failed to deliver. Im at a point where i just want to close off my account and part ways with homechoice. This is really heart breaking and sad as i have been a very loyal customer.
