Enough is enough

ENOUGH IS ENOUGH I TOOK A WIFI ROUTER CONTRACT LAST YEAR. AND A WEEK SHORTLY AFTER RECEIVING THE DEVICE AND SIM IT STOPPED WORKING. I CALLED AND I WAS TOLD A ********** ACTIVITY WAS DETECTED FROM MY ACCOUNT AND WILL FIX. UP TO THIS MINUTE NOTHING WAS DONE BUT THE COMPANY KEEPS DEBITING MY BANK ACCOUNT. I ALWAYS HAVE TO REVERSE DEBIT ORDERS SINCE I HAVE NO SERVICES MY ROUTER. THIS IS BADLY AFFECTING MY PERSONAL CREDIT HISTORY. PLEASE HELP. I'M TIRED. AN AMOUNT OF R3100 HAS GONE OFF MY ACCOUNT FOR SOMETHING I'M NOT USING.
