Smilelove Caused my Teeth to Chip!!!

I had very high hopes to be able to straighten my very slightly crooked teeth. My teeth were straight enough that friends and family thought I was crazy to even spend the money that smile love charged for aligners (and they are much cheaper than the rest). After all was said and done, I thought my teeth would look perfect, after all they were barely crooked...Well they looked ok, a little better, but nothing outstanding. My real issue is how the aligners started to make my teeth chip! It weakened them to the point that 2 of them chipped. The first tooth to chip isn't as noticeable in the picture bc it was from a couple months back and I didn't correlate it being from the aligners at first and it has smoothed out a bit since. The second tooth that chipped was very significant and I realized it was from the aligners bc it was a little more sore when I would put the aligners in...maybe it was cast incorrectly? Either way, I reached out to smilelove with my issue bc I refused to continue to wear the aligners after 7 months bc I didn't want my teeth to continue to chip. I am still paying for these destructive aligners, but the response I received was that maybe I have the type of saliva that weakens my teeth and that's what caused it. They were very polite but basically said it's my fault and that maybe I also didn't brush or floss enough too. I explained I don't have weak teeth. I have had 2 cavities in 30+ years, I brush 3x a day and floss religiously. They also explained that bc I went through affirm to finance that there is nothing they could do bc they were already paid...very mad! Please beware!!!
