Received a call from this number today, they left a message, stated that they were calling on behalf of best buy to see how I am enjoying my new home theater..  Only I have not purchased a home theater.  Hopefully it was just a wrong number.

This is a Best Buy number.  I called the Geek Squad to get a quote and they called back with this number.

Got a call from this number from Anna K  telling me that my MetroPCS cell phone contract was disconnected and to call back at 8888638768. My cellphone was never disconnected and has been
paid on time.

Received a call from MetroPCS about the newly purchased phone. They were letting me know that although I was told that my phone could be unlocked, it can't so I need to resolve this. Calling the number does not work but I will call 611 on my phone. She left her name and ID so I suppose it's a real contact.

I received this call at my place of business, an authorized MetroPCS dealer store. The woman calling claimed to be a local MetroPCS customer but the number belongs to NCO CUSTOMER SOLUTIONS, with a Texas based area code, however my store is located in Florida. The woman spent over 20 minutes on the phone with me asking me very strange questions that customers would not normally ask. I feel that it may have been some kind of inside quality control / "secret shopper" type of situation.
