POOR SERVICE EXPERIENCE

I ORDER A R1000 WORTH OF GROSERIES FROM THE 60/60 APP AROUND 9 AM FRIDAY THE 25TH. THE ORDER CAME ONLY 3 OF THE ITEMS WAS WHAT I ORDER THE REST WASNT MINE. I CALLED THE CALL CENTRE ADVISED THEM OF THE ERROR. THEY ASKED FOR PHOTOS OF THE ITEMS, I SEND IT TO THEM, GAVE THEM THE BAG NUMBERS. THEY SAID MAM WE WILL CREDIT YOUR ACCOUNT AND THE WRONG ITEMS YOU RECEIVED PLEASE KEEP IT. (THIS WAS NICE OF THEM) I THEN LATER EMAILED THEM ASKING TO CONFIRM WHEN WILL THE CREDIT BE DONE. THEY CONFIRMED SOON. ON MONDAY I ASKED AGAIN THEY SAID 24-48 HRS FROM TIME TICKET IS CREATED ITS NOW ALMOST 6 DAYS LATER AND NO CREDIT. I CALLED THE CENTRE EARLIER ASKING ME FOR THE BAG NUMBERS I DONT HAVE THIS ANYMORE I THREW IT OUT AS I WAS UNDER THE IMPRESSION THIS MATTER IS RESOLVED. I GUESS NOT. THIS IS THE WORST SERVICE I EVER RECEIVED, I NEVER AVE ISSUES WITH YOU CHECKERS BUT THIS IS NOT ON!.
