losing it

why is my profile locked when i call your ***** department and why are my transactions blocked each time i try to transact with my credit card... i don't have the time to be calling standard back all the time. in the past 2 months i have called the call centre maybe 30 times , i keep on being told that i have to confirm every transaction that i do with my credit card as standard is trying to protect me.. if standard bank is protecting me why don't they protect me from all the ********** debit orders that go off my account every month which they cant explain! please stop blocking every transaction that i do with my credit card, it is really inconveniencing me .
