Wont help me protect my money

Hi, <br> I bank at Capitec bank for a long while now. I never had any problem with them except for now. I feel that I have been ****med buy an online web site. I bought a product for R15 last month. They have taken it upon themselves to debit my account with R425. I never asked for this or agreed to it in any way. <br> I went into the Capitec Bank this morning and they were not even interested in my request to return this debit. I am shocked that Capitec will not help me protect my money. I just can't believe it. I have no option but change banks now because any one can just debit my account. <br> I am so irritated and disappointed not mention that I am R425 out of pocket. <br>
