Bad, bad polish

Hm, something I don't like is if a polish discolor my nails. Recently I painted my nails with the turqoise polish Nail him from H&M. I loved the color on my nails, it was smashing. But when I removed it after wearing it for two days, my nails looked terrible. My nails were so stained although I had done everything right. I used base coat, I use a remover without oil and and I don't rub the polish when I remove it. I know how to take care of my nails.

So, I went back to my local H&M where I bought it and they took it seriously. They treated me to a manicure and gave me money for the bad polish, not much but still. And they contacted H&Ms quality department.
And right there, H&M failed. The quality department say that it is nothing wrong with their polish, that they have done all the tests and that I must have removed it wrong, used a remover with oil och didn't use basecoat. So they blame me.

But hey, I know I did things right, the problem is the polish. Look at my nails and see.

It is the polish to the left that destroyed my nails.

Sorry for the bad photo, I took it with my phone.
