Worst bank on the planet

Allowed me to go into overdraft without any permission. Bank balance was checked frequently. Eventually I realised it had not changed after a transaction. Checked balance again and again. Tested it out and was allowed to swipe well over my current balance. This after I had phoned in an told them not to allow my credit card to go over it's limit under any circumstances since it had done so the previous month and I was out of pocket due to reckless lending by standard Bank. Phoned in at least 5 times last month to ensure they weren't going to ***** me over again. All calls are recorded but I'm sure those recordings will conveniently disappear. Was told it's my responsibility to check my credit card balance. Which I did. Surely it's their responsibility to respect my wishes? After asking them more than once to keep my limit where I wanted it to begin with? Was also promised a text message every time I use the card, never happened. After 10 years of being a loyal customer I am officially done. Will pay this card off from these reckless lenders standard Bank and find a bank that at least has some form of morals.
