im having this same problem and never even connected it to david's bridal untill i read this forum but i bought my wedding dress there over a year ago and have been gettin call after call from this number for weeks now!
This number called me today.. I find that it is related to me registering for a bridal show or with Davids Bridal. The other numbers that have contacted me in this context include: 8046651471 and one more number that isn't on my call history anymore. Watch out!
Same thing happened to me I was at a bridal show and this number just keeps calling me and hanging up several times a day. When I call back I get the same thing, it says voicemail is full.
