Very Poor Customer Service.. I need to Beg Mr. PRICE to give my money back.

I have received the worse customer service from Mr. PRICE.,I FEEL DISSAPOINTED AND DISGUSTED TO SAY THE LEAST. I MADE AN ONLINE ORDER ON 29-06-20 AND ACCIDENTALLY MADE PAYMENT TWICE. I IMMEDIATELY CONTACTED THE CUSTOMER SERVICE DEPARTMENT AND SEND THROUGH MY PROOF OF PAYMENT, WHERE I WAS TOLD THAT REFUND WOULD TAKE 7 TO 14 BUSINESS DAYS. I FOLLOWED UP 4 DAYS LATER, JUST TO FIND OUT MY REQUEST FOR REFUND WAS NEVER PROCESSED SINCE THEY HAVE NEVER RECEIVED MY PROOF OF PAYMENT ( YET NO ONE FELT THE NEED TO INFORM ME TO RESEND BANK STATEMENT) AGAIN 4 DAYS LATER NOTHING I SPEND ALMOST 5 TIMES ON THE PHONE DEALING WITH AGENTS THAT SO RUDE AND IMPATIENT. TODAY IS DAY16 STILL WITH NO REFUND,, STILL NO FEEDBACK,, EITHER TELEPHONICALLY OR VIA EMAIL. I FEEL AS A CONSUMER THIS IS SO UNPROFESSIONAL AND UNFAIR TREATMENT TO ANY CUSTOMER. CLEARY THE SERVICE YOU PROMISE IS NOT THE SERVICE U DELIVER.. I'M OFFERED A VOUCHER, WHICH MEANS THEY WILL STILL GET THE MONEY BACK AND HONESTLY EXPECT ME TO SHOP AT MR. PRICE AGAIN AFTER THIS EXPERIENCE. IT'S AS IF YOU NEED TO BEG THEM FOR YOUR OWN MONEY BACK.. I'M ACTUALLY SHOCKED AT THE LEVEL OF POOR CUSTOMER SERVICE..
