BAD EXPERIENCE WITH YELLODATA

I CANCELLED VIA EMAIL AS THEY DEDUCTING MORE THAN WHAT I AGREED TO. YET THEY STILL KEEP ON DEDUCTING AND ON NUMEROUS ENQUIRIES THEY SAY THEY HAVE PROBLEMS ON THEIR SYSTEM. THIS IS UNEXCEPTABLE. STILL WAITING FOR MY REFUND AS FROM JUNE 2017. PROOF OF DEDUCTION WAS EMAILED TO YELLODATA!!!!!!!!!!!! WIL NEVER REFER ANYBODY TO THEM!!!!!!!!!!!!!!!!!!!!
