Capitec's **** service

Am very disappointed and angry.. i went to Capitec Bank Crossings Nelspruit to report some deduction that i didn't authorize. I first called and i was advised to go to the branch. Firstly, the consultant answered her cellphone in front of me and apologized after she finished her business, while sitting infront of her...i told them that this is the second time this deduction happens and i dont want my card to be blocked as i paid R70 to replace it the first time it happened..i was given an option of either i block the card and get the refund or i pay another R70 for a replacement....i told them that i will cancel the whole account after getting my refund..another consultant jouned and told me to contact the company that is deducting from my account..i dont know that company ,so how will i find their contacts??? So,Capitec is telling me that evertime an unknown deduction happens, i always have to block the card and pay R70???
