xfinity scam

got a call this morning offering me a new discounted program for seniors. Caller (who identified herself as "Olivia [Edited: "Personal Information"]") called from a local number-i didn't recognize--but answered phone anyway; stupid me!

She asked for feedback about xFinity, and I told her that I felt it was too expensive. So, she told me about the Essentials Program, whereby I could qualify for either a 30 or 50% discount on my current plan once my eligibility was verified. She wanted me to sign up during the call, and I said no--i want to see the offer "in writing" before I agree to accept it. She said she would email it to me in about 15 minutes as we ended the call. She also asked me if I had had any problems with internet speed - I said periodically.  She said we'll send you a new modem and asked if I wanted to install it myself, or did I want a technician to come and install it. I opted for the technician, and we set up a date. I had asked earlier in the conversation if any of my internet speed or mobile plan would change, and she assured me that it wouldn't. Then [ I may be juggling the order of these steps], we went through several sending 6-digit codes to which I responded to verify and to get the detail that I requested. She wanted to check and make sure she had all the info about my address (but asked me to repeat zip code), phone number , etc. Then, she asked about using the same bank account as previously billed, and I said yes. she asked me to identify it by last 4 numbers and type of account. I couldn't remember which account I was using (credit or debit) but immediately realized it  was an auto deduction each month, so confirmed what it was. Then, she reconfirmed all of the identifying information, but asked for SSecurity number --but only last 4 digits of that. Note: all along I was getting gut reactions that I might be being scammed, but ignored them. She put  me on hold to make sure everything was ready to send to me; during that time I googled both the incoming phone number and the special customer service number (for this promo offer). Neither phone number came up  with any association to Xfinity. When she came back on line, I confronted her about it, and she told me that the numbers were good, and I could check with "regular" customer service at Xfinity. at that point, my gut was screaming at me "YOU'VE BEEN SCAMMED". I told her that I felt she was scamming me (which she denied), and that I was hanging up on her. She tried to get me to stay on the phone, but I hung up. About 10 minutes after that confrontation, I got another call from another local number I let go to voice mail; the message was saying my name and "can you hear me" or "are you there" or something like that. So, seems like scam partner was trying to seal the deal. Had work to finish up, so did that, and thought... I better check my bank account. Sure enough those  [Edited: "Language"] had already processed a payment (labeled as an order that I placed in email update) for $179.  I contacted Social Security - got bounced around because of limited hours and staff. Also, recorded message noted that I should have been contacting the Inspector General's office regarding "fraud". To make matters worse, their hours are 8 - 4 EST, so I was too late to reach them today.
