revelationaudio labs cable never delivered

hi
first ,I apologize if my english is not exactly what i would try to explain
i am yves from france ,would like to share here my disappointment,not to be respected by a company ( or maybe a man ,think he is lonely ) who is not delivering my pair of cables purchased and paid since 8 january 2017, Db25-umbilical power for mc intosh preamp 1100 usd the pair
the no respectis not because of a constant postpone lead time but  is coming from the communication ",always saying ready next week ,it is in the  cooker for the best"
promise,and then nothing
at the end I asked this guy "Brad Vojtech " to refund my paypal account ,then no answer ,what should I think

as anyone the same poor experience with revelationaudio labs,wants to know I it is a bad luck story or if this company is a rogue one ,
thanks 
best regards
yves
