Same thing with me. I'm also a rep and they called me.

So just just received two calls from this number and after reading these comments everyone keeps saying that it's supposed to be Home Depot calling back with call back assists. The weird thing is... I work for homedepot.com as a customer service rep and I obviously didn't call in requesting them to call me back... So... Riddle me that!

Calls at least every other day.

I just received a call from home depot from this number on my private cell and the person said she was looking for a John Mitchell. Well I don't know anyone named John Mitchell and I asked her why she would be calling my private number and she responded that my number was listed as the referral number this John Mitchell. Interesting....ugh hope they don't call back.

I too called Home Depot today and requested a call back so I wouldn't have to wait 6 minutes for a service rep.  So far I have received 2 calls with no one on the other end.  I have put the number on my Reject Calls list for my phone.  Hopefully they don't pass numbers on to other entities.

I've been receiving calls to my personal cell phone number from people all over the country looking for Home Depot.  I have called Home Depot and asked them to figure out why my personal number seems to be given out to the public.  They stated that they could not find any record of this happening.  
I have had the same number for almost 12 years now, and have only recently been receiving these calls for the last year.  A few people have called looking to verify employment or check the status of an order.
I have to tell everyone that they mis-dialed the number.  Please, please, PLEASE Home Depot, figure this out and fix it!  If you want to pay me to take your calls that is one thing, but get this taken care of now.

800-910-6704 One of Home Depots routing numbers. (Ogden Utah, Or kennesaw GA)

Whenever I get a call from an 800 #  I always answer.."This is Detective Patterson, how can I help you"  Then if they give me any static I tell them I am calling from an active crime scene, and the number they called is that of the dead person, and how did they get this number.  I saw this once on a youtube video and it was AWESOME!!!..you can drag it out and really have fun..but you cannot snicker or laugh..as hard as it is.

I too was expecting a return call from Home Depot.  When I answered it was disconnected.

Several calls at 15 to 20 minute intervals came to my office desk phone.  Each time I answered and there was no response.  After 18-20 seconds the caller disconnected silently.  I suspect it could be from Home Depot since I had requested a call back for a problem and have not heard from them.
