Bad service and you don't get what you pay for

I ordered a recon 2.5 dieselninhector from these people in randburg. Got the wrong one and not in working order either... struggled to get my injector back from them which they also gave me a wrong and more broken one back... service is bad when it comes to the sales lady and no correspondence within the company.... I needed a 2.5 injector and I got 1.9 whereby they took my 2.5 and send it back with a broken 1.9 after refund ... how the hell!!!
