[Resolved]  Tyremarket.com — Only 3 tyres got delivered instead of four.

I've ordered for four tyres and only 3 got delivered. When I contacted the customer service they are saying that it will be delivered when the stock is available, why did they took the order if the stock is not there in the first place. What made me really disappointed is that they are not even telling me on approx what date they can deliver the other tyre, and I don't have any purpose with only the three tyres. Why did they ship the order partially in the first place. I don't get it. It's a very pathetic and unprofessional experience from tyremarket.com. It's my first purchase and I regret to not buying from the store nearby.
