Worse customer experience ever.

I bought a servers west gate ufo . for my hallway, the measurements I took were incorrect. I told the consultant who assisted me to buy the server I made a mistake . Since the servers is bigger The space interned for . She advices that the store does not do returns or even reimbursed the consumer. I was so stressed since am busy with a renovations and laps of judgment is costing me so much. I was made to feel like it was problem that I bought the server. And I should deal with it. I called again she confirmed that she talked to the area Manager and store Manager. They advised I should bring the server on Wednesday for an exchange. I told her I will look for something in the store , I did not find anything. I asked since I can’t find anything can I get my money back she said no. I asked if I can get even if it’s voucher she said unfortunately no. She then said I have until Sunday to make up my mind to take something in the store or go to a ufo branch look for a server. I did go to the different branch I looked for the servers but unfortunately I did not find anything that matches with the theme I had in mind. Before all this I did read the terms and conditions. As customer the service I received was bad. I was forced to settle for products that I did not want . I explained to the sales lady how I feel all she said she is doing her best to assist me. So when I told her am going to report this service to hello peter only then am I being told the options of getting my funds back. On the day I went to drop of my id copy and bank statement she was not there. I told the Manager but it seems he was aware of the whole thing. But all got is the process. How about me as consumer we were looking in buying the couches but after this service. I do not think they deserve our hard earned money . If they can not resolve a simple matter for client without making clients feel they doing me favor to reimburse me.
