Very bad service from Grabitall

I ordered goods from grabitall on the 28th of April and there were supposed to be delivered in 9 to 10 days time. After waiting for weeks , i wrote to them and i was told that the warehouse is moving hence the delay. 2 weeks after, i have not heard anything and i wrote form them again and Coburn responded saying he will get back to me. Up to date, i have not heard anything. On my first order with them some of the goods ordered were not delivered and i was told it was because of supplier had run out of stock. Why sell goods if there is no stock? This is the worst service i have had from online buying.
