Unprofessional and Poor Customer Service

I spoke to a Online consultant Charlene Dourie, where I app**** for an Online Cellphone Deal, <br> I did the application where she requested all my personal details where I provided her all details.<br> When I provided her my Bank Account details the phone call got cut, I've called the Online Sales Center 5 times where I left 4 messages to speak to Charlene Dourie, but she did not come back to me, after the 5th call from me I got hold of her and she told me that she will call me up until this very moment.I am not sure what her plan is with my personal and Bank Account details I supp**** but should any ***** get linked to my name or any Debit's from my Bank Account, I will definitely sue Charlene and Vodacom.
