PATHETIC - NOT TRUSTWORTHY

Reservation *** I have been struggling to get a refund from booking.com since apr - they advised they did the refund 15 May and it takes up to 30 days, however still nothing - my bank can not trace it on the ref no they gave - I HAVE BEEN ASKING THEM TO SUPPLY ME WITH THE ACTUAL PROOF OF PMT OR THE BANK DETAILS THEY USED TO DO THE REFUND - BUT TO NO AVAIL - THEY KEEP GIVING ME THEIR REF NO AND I KEEP ADVISING MY BANK ARE UNABLE TO TRACE IT ON THEIR REF NO...........THIS HAS NOW BEEN GOING ON SINCE 15 JUNE AS I WAITED OUT MY 30DAYS..... BOOKING.COM IS NOT TRUSTWORTHY PEOPLE AND PEOPLE SHOULD NOT BOOK THROUGH THEM.....I WANT THE BANKING DETAILS THEY USED TO DO THE REFUND AS PER MY BANK'S REQUEST.......NOTTTTT THEIR REFERENCE NUMBER AS MY BANK CANNOT TRACE IT ON THE NUMBER THEY GAVE......AN EXACT COPY OF THE PAYMENT THEY DID.....EXAMPLE - DA LATEGAN - FIRST NATIONAL BANK - CREDIT CARD NO ..............................
