Customer not receiving proper service

On suturday I bought the machine, and I sow that it's will not meet my needs. Yesterday morning I returns the machine and I was assistant by the gentleman namely Artwell madondo he checked the machine if it's in good condition and he was comfortable with its, he promised to call me back with the feedback, Since yesterday no communication between my self and Artwell, This morning I called to find out about the process, he was not helpful and he promise to call me back around lunch time. It's 2:40 and nothing from Artwell, I believe the guy is not fit and proper to deal with customer service hence no communication between him and my self. Builders if you have staff that treat customers like this you will loose businesses
