Poor customer service

Its been 3 months now trying to cancel laybye at Sterns Jabulani Mall. Firstly they had issues with the laybye system. I went back more then 3 times and I was told that. 3 weeks back I was told that they don't have R800 and I should leave my number and they will call back. No one called. A week ago, they had R700 and they could not give me that amount as they said they must give me a full refund and again they promised to call. I was expecting a call the next day as they were not far from making my refund of R800. Still no one called. Today I decided to go back and I am still being told the same story. The manager does not even apologise from being a ****. They still will not call. It looks like I will be sleeping in the store today as I am not going anywhere until i get my refund. I have been understanding as I am the one canceling the laybye but now they taking me for a ride.
