TERRIBLE SERVICE

I am very unhappy with the service received. I made a mistake and accidentally lowered my overdraft on Internet Banking and when calling the call centre, they said they couldn't help me I should go into the branch. I went into the Epping branch and they again told me they could not help me. It was ABSOLUTELY shocking. If it was not for someone eventually helping me I would still be in a negative balance. They made me feel like it was all my fault, the branch manager at Epping Branch actually told me that if I complained over social media I would have a very quick response, can you believe it. The service was shocking to say the very least
