Bad turnaround time and customer service

In sumarry, my banker was kn leave when I sent an email asking for an overdraft increase. She had an out office reply stating who to contact while she was away. Sent that person an email on the 14th Dec at around 7am, i called the contact centre to ask for assistance in the afternoon and they tried connecting me with him to no avail and said they would forward my details to him so that he can get back to me. Day passes no call no email reply. I call the contact centre again on the 15th and they eventually connected me to him, only then he replies to mail and i ask when should i expect this to resolved, he stated that if i fill in the documents by around 10am he will increase the OD by 2 or 3pm or send a mail about whether it was successful or not. 3pm passes no reply, i then check if the OD increased, nope that either was not attended to.

Utterly dissatisfied because we pay for these banking services for individuals to treat us like second class. On the minimum why was there no email reply to state that he could not do it or he will sort it out by this date. Unprofessional to be honest.

3 days later still have not gotten what i had asked for.
