Query: Melted in dryer on low/delicate setting

I had no problems the first time I washed this mattress pad, but several holes were formed when it melted the second time I washed and dried it. About ten holes opened up along the sides where the polyester melted. I washed and dried it on low/delicate (I even verified this when I saw the holes). It was still damp after the first drying cycle, so I dried it a second time. Perhaps this was too much and made it melt, but a damp mattress pad is of no use to me.I put the pad on the mattress anyway, and some of the holes became larger as I stretched the sides to fit over the mattress. I will probably throw it away soon. I am very disappointed that I only got to use it for a couple of weeks and I do not recommend this mattress pad to anyone.
