could not make-out what they where saying. this is the 3 rd call in 4 Days

a scam  I suppose

This caller identified herself with Dish Network. The connection weas not very clear and she had an accent that was hard for me to understand.
She was offering an upgrade to me dish equipment; knew the amount i paid for my services and offeerd a discount to my Dish bill doe 10 months to cover the cost of the new equipment.
I was suspicious and called Dish Network. They advised that my equipment was not obsolete and there were no current offers to upgrade equipment.

This looked like a scam, and still does.

I received the call indicating DISH Network... Wanting to up grade my system and collect money up front.  I called Dish and they verified this is a SCAM.

Definitely a scam.  Just spoke with Dish Network.  The gentleman on the phone was very, very pushy and I told him I was busy and I would call back.  He told me he would call me back in 30 minutes.  He called 5 times in a 15 minute span and we didn't answer.  Hold on, they just called again!  Now my husband is on the phone with him and we know it's a scam.  My husband just told the guy he was going to punch him in the face.  Definitely don't give out any information!  Not your security code or answers to your security questions.
