Pretty Polly Tracking Order Status

I bought 5 packs of nude coloured knee highs recently because the colour was good and they were 8 denier - perfect for warm days. When I tried a pair on the collar part which is meant to sit below the knee was so tight it marked my legs and was very uncomfortable. I have thin legs and have never encountered such a vice like grip before. When I complained I was told to return the packs for refund but not the ones I had tried on. Refunds could only be given for unworn items. Or faulty items. But how would I know they were so unpleasant to wear unless I tried them on? In my opinion they were unfit for wear and thus faulty. The customer service was non existent despite a number of e mails being exchanged. The knee highs cost £6 a pair and the ones I could not return are completely useless to me. I would not recommend Pretty Polly for the dismissive attitude to customers.
