Incompetance, Commiting Fruad

I cancelled my package in 01 FEB 2020 (my contract expired, and I refuse to renew) I received notice of cancellation for 21 Feb 2020 and still my account are being debited? In fact you still owe me R140 that was deducted in March, and just now I receive another invoice for April? The incompetance is remarkable!! I have so many email correspondence betweet staff members Zoliswa that confirmed the acc is cancelled and closed. Then Zoliswa even asked for my bankstatement to see that there was a debit taken in March, everything was sent, and yet another invoice from Telkom! You are busy comitting fruad, I gave no permission to debit my account!!!
