Received wrong phone scam call from [Edited]

You have scammers hacking into your customer database?  How else would someone know we recently received a new cell phone at our house?  [Edited: "Invalid Phone Number"] called to tell my husband the phone he received was incorrect and we needed to take it to the UPS Store to return it before his correct phone could be shipped out to him.  The one and only piece of paper in the box had very little information on it but did have name, address and a phone IMEI # printed on it.  No color, phone type, etc.  The box the phone was in had a different IMEI # printed on it, so with 2 different numbers, how are your customers to know there may not be an issue?  I ended up speaking to customer service on behalf of my husband.  I refused to go anywhere and no, I don't have a printer to print your label so someone can pick it up.  You made the mistake, you fix it.  I deal with shipping companies all the time and know they can be sent out to retrieve something.  The phone was left on the porch as they were figuring it out and someone would come retrieve it.  Thankfully, the scammer must not have had a person in the area to retrieve the phone or it would have been gone.  The scammer called back today and I ended up giving him my phone number as they were still trying to figure out how to get this incorrect phone returned to them.  My husband got tired of all the mess and took the box to the Xfinity store today.  They assured him it was the correct phone.  Nobody seemed concerned of the scam.  Supposedly none of their other customers have experienced this event.  I don't buy it.  The main point:  Someone other than Xfinity has our customer information and they're using it to try and get new phones shipped to them.  We're about done with Xfinity.
