Need answers ASAP

I called in last week to request for my invoices of items purchased from Homechoice within this year and I only received them today but it wasn't all of them. I tried calling and everytime the phone is answered nobody speaks. When the times for customer service they are open until 7pm. I understand it's a Friday but I've waited for almost 2 weeks for my query to be solved and I'm still waiting for a call on my bed that I want returned. Can somebody assist with my query because right now I'm fed up and tired of always fighting with Homechoice.
