WORST SUPPLIER ON THIS PLANET

I HAVE A QUERY UNANSWERED SINCE FEB 2013- THEY OWE ME A REFUND OF ALMOST R4000 FOR A BRAND NEW FAULTY ****LE AND OVERCHARGE OF DATA. OF COURSE AFTER A NUMBER OF PHONE CALLS, EMAILS- NO ONE HAS DONE ANYTHING TO ASSIST. (AND A NUMBER OF OTHER ISSUES THAT I DON'T HAVE THE TIME NOR ENERGY TO DISCUSS AGAIN)!!<br> NOW, I WANT TO CANCEL MY CONTRACT AND WHEN YOU CALL THE CALL CENTRE THERE IS NO OPTION TO CHOOSE CANCELLATIONS- BECAUSE OF COURSE THEY WANT TO MAKE IT AS DIFFICULT AS POSSIBLE FOR YOU!!!! SO WHEN YOU EVENTUALLY GET THROUGH TO SOMEONE THEY TRANSFER YOU AND YOU HOLD AND HOLD AND HOLD- I HAVE DONE IT TWICE THIS WEEK EACH CALL 30 MINS WITH NO LUCK OF GETTING THROUGH. AND CANCELLATIONS DON'T OPEN ON A SATURDAY BECAUSE THAT WOULD MEAN OFFERING SOME SORT OF CUSTOMER SERVICE AND THAT IS CLEARLY NOT PART OF THEIR BUSINESS STRATEGY! I HAVE SENT QUERIES ON THEIR CONTACT FORM AND SURPRISE SURPRISE NO ONE REPLIES. THEY ARE THE WORST COMPANY I HAVE EVER DEALT WITH, I AM FACED WITH NO CHOICE NOW BUT TO CONTACT MY LAWYER TO SEND THEM A LETTER!
