Debiting my account without giving them permission

My bank is FNB, on the 24 of April my account was debited R299 by Digicash PTY LTD. Today i went to my bank to get clarification as to who is this Digicash, was told that it under ABSA bank so i should contact them. <br> <br> I dialled ABSA Digicash PTY LTD and they told me that they were debiting for another company, and the company name is 'Mapzocode' , when i called this Mapzocode they told me that they are a Telemarketing company. I was so irritated especially by the fact that i have never taken any thing to any stores or over the phone.<br> <br> And in future i will not even give these people any opportunity to even start the conversation because they are **********. I had to go through such trouble ( my airtime) for something that i did not do and my money was taken. <br> <br> I work very hard for someone to just come and take my money without my permission!<br> <br> Please i need this resolved as soon as possible.
