Hi, any idea on how much longer it will to get my questions answered?
Customer: replied 5 months ago.
Hi, I'm sorry to keep bothering, but I only have about 40 more minutes to submit my answers on my questions. Will my questions be answered before then?
Customer: replied 5 months ago.
Please, can someone just tell me if my questions are being worked on and if I will get them within the next 40 minutes. The answers are useless to me if I don't get them before then. PLEASE!
Customer: replied 5 months ago.
I would like a refund of my money! This was of no help to me at all. I am not satisfied at all!
