Hey Laurie! I am sorry to hear about your troubles. I actually think you should do a factory reset on your phone if you have not found a solution for your problem yet. Unfortunately, doing this would completely delete everything in your phone, including contacts, pictures, and any other files you might have on the phone. I will attach a link to a video that will give you basic instructions on how to do the factory rest. Just make sure you save everything on your phone before doing it, IT WILL DELETE EVERYTHING.
Another piece of healthy advise. Dont ever buy blu phones. They are cheap Chinese quality stuff that does not ever last more then a year, and thats if you dont even use it that much. I am not sure how much you paid for that phone but i can tell you that i can go right now and buy a brand new one for $25. That just tells you how long its going to last.
Well i hope this helped! Any other questions, Please ask!
