Double debit order

I HAVE A HUGE ISSUE WITH TELKOMS INCORRECT BILLING, IN MARCH I AHD ADJUSTED MY SPEND LIMIT TO R650.00 TO USE AIRTIME IN MARCH...IN APRIL I GOT BILLED FOR IT WHERE THE AMOUNT ON MY DEBIT ORDER HAD COME TO R939.58 WITH MY REGULAR CONTRACT PAYMENTS, SO MY SPEND LIMIT SHOULD HAVE BEEN SET TO 0!LATER IN APRIL I NEEDED MORE ON SPEND LIMIT LOGGED ON TO ADJUST AND NOTICED THAT MY SPEND LIMIT WAS ON 650 STILL! YET I HAD ALREADY BEEN BILLED FOR IT ...I THEN CALLED TELKOM WHERE I WAS TOLD THAT THEY HAVE TAKEN THE DEBIT OF 650 SO IF I ADD MORE TO MY SPEND LIMIT NOW I WOULD BE CHARGED FOR IT IN MAY SO I ADDED MORE TO MAKE MY SPEND LIMIT ON 850 WHICH SHOULD HAVE HAD 650 TAKEN AWAY ALREADY BECAUSE I ONLY WANTED TO ADD 200 BUT STILL SPEND LIMIT WAS ON 850 BECAUSE TELKOM NEVER CLEARED THE 650 I HAD ALREADY PAID FOR AND TOO MY CONTRACT HAD EXPIRED IN APRIL FOR NUMBER *** AS TELKOM THE GLEN TOLD ME I SHOULD COME AT THAT TIME TO CANCEL MY SMART 100 PLAN IN WHICH I DID SO I GOT THE FORM FILLED IN AND GOT A REFERENCE WHICH I HAVE...YETG FOR MAY I STILL HAVE SMART 100 PLAN ON MY NO REPLY STATEMENT FOR 99 BUT THIS WAS CANCELLED! SO TEL ME WHY YOU WANT TO DEDUCT 1300 THIS MONTH YOU ARE DEDUCTING ANOTHER 650 WITH APRILS CHARGES FOR MAYS PAYMENT WHICH IS MONEY YOU ARE *****ING OUT MY FAMILYS MOUTHS AND STILL CHARGING FOR CLI which I DONT get no caller ID still Which TELKOM guys said you cannot fix as it is a data sim card but i still get charged for it so lets summarize this 1.i am getting charged 2nd time for a payment which you have already debitted 2.i am getting charged CLI service which i dont even have 3.and i am getting charged for a smart plan 100 which expired and was cancelled For me i have enough to take telkom to the small claims court for a civil lawsuit againest telkom with all my reference and proof I am sick and tired of telkoms incompetance and will make a claim for a pay out with damages done to me as a client as telkom has been mis managing my account and not sorting their billig correctly
