Hunters fitment center is shocking

First of all the first purchase I ordered an engine from them and the wrong one was supplied . Then I ordered a gear box and flywheel and the flywheel was incorrect . I have sent the flywheel back 3 weeks ago and I am still waiting for my refund. I have called numerous times and my calls dont get answered. Eventually cameron said last week that payments have been processed and I was suppose to receive the money by friday . Monday this week I called the lady in charge of finance and she has heard nothing of refunding me and now no one seems to know what is going on. I have never dealt with such bad customer service and such rude people in business. I will never be supporting this company again and I am hoping to get my refund before the end of this week
