Looked local, hung up before I could answer so I called back only to get a busy signal... Tried again in a few minutes and was disconnected

I got a text from this number yesterday morning.  It said "Fred and Kelly are getting married... wanna go?".  I tried calling back to say they had texted the wrong number but got a busy signal twice and all systems are busy voice message the other time.  Strange...

Answered but nobody on other end.  Called the number back using Google Call, to hide my real number, but the number just rang repeatedly with no answer.

Called and said they were calling from CRS Mail a private mail company out of Toronto confirming a mailing address as they have received mail returned to them

Man with heavy east-Indian accent called. Said my computer was going to crash and he could help stop the problem. Scammer. Hang up.

Several calls received; they have both mine and my husband's first initial and last name. They hang up on my husband after confirming our initial and last name. I don't pick up when they call. When the answering machine comes on, they hang up. Several calls were received where there is silence on their end.
