Appalling service and empty promises

What appalling service! I placed an order online in March with a 21 day delivery promise. The order was for my husband's birthday, and I made sure that the item would reach me by the correct date (public holidays and weekends taken into account). It is now the 19th of June and I am still being offered excuses and apologies (if I am lucky enough to receive a response to my correspondence at all, which, more often than not, I do not). At times I have emailed every single day, trying to get an update on my order, only to get a response after a week of pestering. And when I do get a reply, it is in the form of: "Hi, I am Mr X and I will ask Mrs Y to get back to you." Mrs Y almost never gets back to me and when she does it is in the form of: "Hi. Sorry. We're still waiting. We'll keep you updated." And I am NEVER updated. I wait a few days before submitting my next bout of pestering emails, only to receive the EXACT same responses. Incredibly frustrating! Perhaps my husband will receive his gift on his birthday in April NEXT year! Holding thumbs!
