Complaints about Phone Numbers785-503-####

Got a call from this number, claimed as tech support from Xfinity; said the cable box has outdated software. They need to do an software update on the box remotely with no TV on and lower my bill $30 a months for 24 months. Claim the software was expensive like $1200 (??!!) and they would only charge $199.12 in which Comcast will send a check to "your door step" every month for 3 months. The stupid operator could not even do the math right and repeated the offer/calculation etc for at least thrice in 7 minutes. He repeated exactly like reading on a paper. He also gave his "Department number" (I found down it was a TextNow number), his extension and batch number. Before getting in to payment, I just asked about the "Department" phone number. He could not answer then asked me to hold for billing department then later for his supervisor. The supervisor said they were interntet company; so, they used internet number (!!??). In short, scam call; no need to answer.
