THE WHITE COMPANY cotton bedlinen after ironing!

Brand new unused-on-any-bed, 200 thread count Egyptian cotton bed-linen, after 8 washes with a Bosch machine that is hardly used plus Persil powder, water softener and fabric softener and Bosch steam ironed whilst wet... on at least four occasions!
I would not even put this on my own bed let alone that of guests!
I took them to a professional laundry service following others' advice, before I consider THE return to THE WHITE COMPANY... but this stupid laundry company have made black blotches on them and folded them differently ... even the original creases can still be seen...
It is at a cost of £14 in addition to the £133 that they cost me.
I WILL RETURN THEM in the original delivery box with all the original packaging,  once I get them back ( hopefully washed again! ) on MONDAY!!!!
I am an unhappy bunny!
