BAD SERVICE @ SSK

I bought 130 PVC pipes, first I had trouble with them about the delivery that was late and they had no feedback on when they would deliver. At last when the PVC pipes were delivered, a lot of them were damaged and can't be used. On top of that they send the wrong products. I am currently complaining to them to come and have a look at the damaged pipes to fix the problem, as I can't go on with my work, because I am still waiting upon their arrival. I have called them several times and they don't bother on making a plan. This whole procedure is going on for 2 months now, and I am very disgusted in their service. I had to pay the bill before they delivered the products, and I paid immediately, but this is the service I get. I did my part, when are they going to start doing theirs??????
