Keeps calling everyday -

I received a called also from this number and let it go to voicemail.  The voicemail message was a gentleman calling from Staples and wanted to discuss improvements on my rewards program.  I did not return call to call back number but it was from +1 888-319-7171 x 6684.  I felt this may have been a scam so I did not return call.

This lady calls and calls and calls.  I tell her I'm not interested and please stop calling me but she calls again and again.  I recognize the number now and just don't answer, but it's still a pain in the butt!

Call went into my voicemail.  The caller stated she was calling from Staples and wanted to discuss the new improvements for their Rewards program.  She left her direct phone number +1 888-319-7171 ext 6684.   I called my local Stapes store and I was told they don't call customers and the new Rewards program came out in July and letters were sent out.  The manager at Staples stated calls wouldn't be coming from Canada since Staples is in the United States.  I guess its a scam and glad I didn't answer the phone.

Called and hung up..........no one on other end of line

no one there but I have gotten calls from Staples before so it may be them
