fed up with standard bank

3 weeks ago I went to standard bank bayside to enquire about my overdraft I was told there was a note on the system and had to contact the call centre. I emailed them on Sunday and was told on Monday that I would have a response within 24 hours. On the Wednesday I emailed again and was told that my query would again be answered without 48 hours. Now, 3 weeks later, 5 emails and many phonecalls later, I am still waiting as it had gone to the sales dept (I have also been told that people will call me by a certain time and they dont). At 1:00 today I called again and was told someone called Amelia would call me by 2:30. At 3:30 I called again and was told that no one can help me so I must go back to the bank. I explained that I had originally started there. Maria in the call centre said that she can't put me through to sales and there's nothing she can do. I am beyond furious.i have been pushed from pillar to post and despite this query been 'escalated' several times, 3weeks later, I am no closer to getting an answer. I was told that head office would investigate anf now I sit being told that they can't answer my query. Hopefully now, someone will respond.
