Hi Tanveer!
Thanks for reaching out! My name is Erin, and I'm a lead on the Help Team here at Moz. I appologize that it took us some time to get back to you, we've been a little swamped! We're a pretty small team (about 8 Helpsters). We always strive to get back to folks as soon as we can, but sometimes it can take us longer than we'd like. The truth is on any given day we're at the mercy of vacations, sick days, a higher volume of requests than normal, and our human needs to sleep and eat. 
We prioritize oldest requests first, so our support is generally on a first come first serve basis. Every request that comes through our gates is important to us, and we don't think it's TAGFEE to prioritize anyone's issue over someone else's. Prioritizing requests from oldest to newest is the most fair way we can cook up to approach support. It looks like David reached out to you this morning, so you're in good hands!
Bryan said it beautifully, we are committed to always getting back to you. We
our users, and making y'all happy is the reason we're here. I can totally relate that sometimes you just want to talk to a Mozzer, but don't underestimate the community! These folks all come from diverse backgrounds, and are a true wealth of knowledge. Depending on how busy we are, sometimes our Q&A forum will get you a quicker response. 
I hope this helps, and happy Thursday!
Cheers,
Erin
