Do you not understand the word cancelled?

<p>I cancelled my data contract with Yello data last year, and even received an sms to say that the account has been suspended... after which they keep debitig my account, on phoning them they said oh they had one more month's debit order that i owed them then they would stop... well that has been 3 debits ago...</p> <p>i tried to reverse and block them on my bank account but they debited me AGAIN this month!!!</p> <p>i don't know what to do!!! Except perhaps see a lawyer??</p>
