Wish complaint: Delivery dates keep getting moved on products

I have waited and waited on some products ordered only to find that their delivery dates keep getting moved forward and more than once on items. I have orders I have been waiting on that had end of May deliveryf dates and now those have changed to June and some of them were first set for April. They do this without asking if I still want to wait or refund my money. I complained and it has been over the 4 days mark and no acknowledgement of my complaint. NO contact and I have asked that all of my undelivered items now be refunded to me via my Paypal account and no reply. I am finished with using them for anything. They have been good in the past and I am sorry that it has come to this but I am 66 yr old and no longer wish to wait and wait and not be told or asked if I want the delivery extended. They have no way or it is well hidden on how to contact them without a costly call as 1-800 from Scotland and other countries besides the USA cost loads of money. I want my money back on all undelivered items via Paypal please!
