First of all I had visited a dentist office about getting Invisalign which they told me they can do it for a much lower price then what another office had quoted me. (It turned out costing the same). I agreed and paid anyways and all my receipts says I'm paying 00 for clear aligners and an expander. 5 months down the road the dentist office calls me and tells me I can't get clear aligners and I have to get braces. Otherwise they'd have to charge me and additional 5 per aligner and I'd need 8. I very reluctantly agreed to the braces because I had financed it and wouldn't be able to get the money I paid them back. Is that legal? I thought this would be considered bait and switch. Another question is the braces took 6 months to put on and take off. Well they give me a retainer and never told me that I was going to pay for it and 7 months down the road I get a letter saying I owe 0 for that retainer. Is it legal for them to charge me without informing me and I never signed anything to agree to pay for it either. Is anything they are doing legal?
