He told me he was from AT&T and wanted to talk about our service (we do not use AT&T anymore.) I told him I could have to call him back as I was busy. He asked if he could call me in 15 minutes, and I said I prefer to call him back. He said hang on, and he would give me an 800 # to call, he acted like he could not hear me, kept saying HELLO,....HELLO, then hung up.
Called my cell several times. When I pickup no one answers. I called back and got the error tone. I got maybe 7-8 calls form this number, one after another.
