WAITING and more WAITING no updates?!?!?!!?

Okay so where do I begin, I placed an order online in December. Instead of giving a warning that there is no stock or there will be delays in Jan because of places opening late in Jan, I had to call and ask for an update, 2/3 weeks AFTER I placed the order. Receiving an email update about one item and getting updates did happen, but she stopped responding after a while. After that, I had to phone them 4/5 times already just to get updates after waiting for weeks, not 2 weeks 4+ weeks. Last time I called was within this week, I begged to get an update on my last time, and all I got was an email asking AGAIN for more documents but NO update. Nothing. How do you guys just let your customer assume? w
