Xfinity iPad mobile scam

Xfinity is being the ridiculous with how they treat their customers. I was trying to get a deal on WiFi being cheaper. So they offer a cheaper with a free iPad . Which it sounded great at first. Then I started reading more reviews on the deal, and looked at my account. It showed I’d be getting charged. It also showed two charges for iPad taxes. Evidently when I accepted the deal, because one chat had gotten lost and reopen with another agent they put in the deal twice. So they sent two separate iPads. I had to send one back and refuse another. I’ve been speaking with xfinity since the first day after accepting because it all seemed so wrong. One iPad has already been delivered back and the other will be there tomorrow. However they’re still saying they have to wait to inspect the first iPad , even though the box is completely unopened. I just keep getting circled around different answers. They say what I want to hear but then change their answer once I question more in depth about it. First it was I’d get my refund within 2-3- business days within returning. Then it turned into I’d get my refund within 6 weeks for returned items. Absolutely nothing they say is credible or the truth. They won’t even acknowledge cancelling my mobile account. I have a feeling they’re trying to make me wait out til 14 days so they don’t have to give me a refund at all. Which is completely wrong considering I sent these iPads back very quickly. I can’t believe xfinity has done this to so many people. I hope someone eventually can help me out with this.
