bad service

I am so disappointed with the service I have received from Standardbank.. I took a term loan from them the 3rd February and paid the full amount plus the initiation fee back the 10th February ( 7days later) I call in to close the account and the lady Mariam tells me I need to close it at a branch.. I work in town and have to go all the way to thibault sqaure which take me more than 20minutes to get there (i only have an hour lunch) I get to the branch and I am told they need to log a closure on the phone.. I then call back and speak to Zintle who again tells me to go to a branch.. I am not a circus to be sent up and down.. they can do the loan over the phonne but now they dont want to close it..so on the day i pay the balance i am charged a months interest (really now) so now I have to pay an extra R530... after paying the balance in full.. I just want to settle this loan and close and I dont see why I have to be sent up and down
