On 19 May 2024 I bought an item on T/m.  It was listed as a 'Louis Vuitton bulldog bag charm.'   I paid $129.45 for the item including $6.50 for shipping.  Item never arrived.  I gave the correct address details.  It was mailed by the seller with Post Haste.  Post Haste have admitted non-delivery was their fault and I am STILL waiting for them to refund the money to me.  I am 86 years old, a pensioner, and this was a huge purchase for me. I want your advice as to how to get Post Haste to refund me.  Maybe hearing from you would help my situation because they are ignoring me.  Thanks in adva...
