Query: So Disappointed

I have used Zip Wax for over 20 years and it was always the best facial waxing product available. I swore by it. Recently it was unavailable at the store where I usually purchase it. I was literally scraping the bottom of my wax pot. So, when I found a new stock of it, I purchased a 7 oz block immediately. I don't know what they have done, but the formula is definitely changed. It is very grainy when melted, not smooth the way it used to be. It does not go on well, and does not take hair off anywhere near as well as it used to. Why did they have to change a product that was perfectly fine and working just as it should, for so many years? I'm no longer going to purchase this product and will have to find something else that works the way I want it to. It is such a disappointment.
