Vodacom IS USELESS AND PATHETIC (The worst customer service I've ever experienced)

I have Called over 20 times to Vodacom, they have been double deducting my installment every month for the past 2 months, I then called to advise them to stop the double DEDUCTION AND TAKE THE CORRECT INSTALLMENT, THIS PERSON CANCELLED MY FIBRE CONTRACT, CLEARLY THE AGENTS EMPLOYED DON'T HAVE LISTENING SKILLS AND PHONE ETIQUETTE. I HAVE AGAIN WASTED MONEY ON CALLING THEM ALL THE TIME TO FOLLOW UP ABOUT THE PROCESS, NO URGENCY FROM THEIR SIDE. IT HAS BEEN 10 DAYS AND I STILL DON'T HAVE FIBRE. THIS HAS INCONVENIENCED ME SO MUCH AS MY HUSBAND WORKS FROM HOME. PATHETHIC SERVICE HONESTLY. THEY ALSO **** ABOUT CALLING ME. I HAVE ZERO CALLS SHOWING FROM THEM AND NO COMMUNICATION. I HAVE Called few times where , THEY DROP THE LINE AND DON'T CALL ME BACK. DON'T T TAKE VODACOM THEY MESS YOU AROUND..WORST EXPERIENCE EVER!!!!!!!!
