Bad Customer Service

I bought a monitor back in November 2017. It had issues so I sent it back to Dion Wired in Kolonnade Mall mid December. I kept calling them from mid January to ask for an update about my product and every week they kept telling me that they had issues with their supplier and that they would call within the next week or in 2 weeks, THEY NEVER CALLED ME BACK! I had to call them every week and ask for an update and remind them that they said that they would call me, but they don't care, they keep doing the same thing.

I finally called them today to ask for my product back whether fixed or not, they got me to talk to the manager and he said he'll call me back after finding out about my product, HE NEVER CALLED BACK!

Please give me my monitor back, I've got work to do!
