Disgusting service requesting assistance since 8 Jan.

I have been calling everyday weekday since 8 January requesting a settlement amount to be sent to me via email and still have not received it. First the excuse was that one couldn't be sent because the statement was closing. The next day when I called I was told that the request was sent and I should receive it the same day. The next day when I called my profile was blocked and could not be unlocked for the day, I was requested to call the next day. On the next few calls I was advised that the letter will be sent. Today I was advised that the number that I have been calling all this time *** (transactional team) is the incorrect department and can not help as the request needs to be made to another department. Please tell me who is going to be liable for the interest accrued from the date I requested the settlement amount to date. In light of the service I am receiving as a current client, definitely will not open the cheque account with standard bank.
