Useless Bank

This bank is totally useless how a credit limit increase on an existing account take 3days. I App**** via the app on Thursday Morning I sent documents required at 8:33 Thurday morning . Phoned Customer service at 15:30 Friday to get feedback consultant informed me that it was approved and a consultant would phone me for final info. No call phone this morning to be told That they are awaiting documentation that was sent and received. And that the matter was escalated to the back office but sorry they do not work weekends. Must wait till monday . This is useless I am a existing customer of over 6 years . My salary gets paid to my standard bank account . How the hell can it take this long. I have app**** for credit with other banking institutions before with turn around time less than 24 hours and i do not even bank with them.
