Bad Service

I brought and paid for goods on internet via my cheque account on 6 October 2015. I only received half my order on 3 November 2015. Only when i called in to check on my order i was informed the other item is out of stock, but no one communicated this with me. I requested for my money back but to date am still waiting for a refund. Every time i call i speak to a different person who tells me they are busy looking into this and i will get the refund but they never know when. I am highly disappointed in the service i received and don't think i will buy from them again.
