Etsy complaint: Can not return or get help.

I bought items that are not fit for purpose and have contacted help and support that did not believe and made me feel like a liar. Continually explained and they did not help. I sent in proof and still they do not see I bought from them. I am shocked and horrified they are so unprofessional and do not want to do returns. I contacted they help in messages and this is because the online service is not easy to do returns so I went to support . I have multiple returns and I can not add all the pictures here please send me a link I can give to the list. Also Etsy sent me pillow cases I did not order and I offered to return them as a good will gesture and I did not want to keep some not paid for. And to be honest I am not sure if I paid or did not because the way they have treated me giving me a bad service. I have statutory right and I have not excepted these good I can happily take the route to contact trading standards also I told them this they still do not help. The white sheets I ordered do not even fit the sizes I bought them for the double bed sheet may not even fit a single mattress the fabric is not good either.
