Place my order on the 26 of October Sunday will be the 26th of November still no order received

Placed my order on the 26 of October, this Sunday coming will be the 26th of November their Policy clearly states that you will get your order between 7-10 working days mine is taking longer and every time I send an e-mail they keep on saying you will receive your order this week from Tashriek Rustin ~ Customer Support Agent, they are waiting for stock from their supplier, I feel this is not my problem they must make sure they have enough stock before they advertise it I can buy the same products cheaper and faster, I am extremely upset, frustrated and this is unacceptable and ridiculous how long a product can take to reach this Company and the fact is that you have to pay before they deliver but it takes forever. I want to know how long must I still wait for my order to be delivered and think Management should step in here, as I keep on getting empty promises.
