Worst Service Ever !

I placed my order on 13 January 2020, on 23 Jan 2020 i received a mail stating that my refund was excepted but i did not even receive my order yet so how can a refund be requested?I received my order 29 Jan 2020 one item missing,the same day i submitted a refund (Store Credit voucher) , after having my items for days on end without collection for refund i phoned nemours times asking for collection . On 24 Feb 2020 they collected processed the items and refund was Approved but still till today i have not received a voucher nor my money back. I have been phoning sending emails with no one responding the only response is a automated response "your request is solved" how in the world is this possible when i still have no refund on my purchase personnel answering the phone can not assist and is giving me the one excuse after the other no after sales assistance worst customer service i have ever received in my life !!***
