Standard Bank won`t allow me cancel a Personal loan electronically or telephonically but approved the loan electronically doesn`t add up

Standard Bank won`t allow me to cancel my Personal loan that I took out less than 2 days ago and giving me the run around and transferring me to the switch board advising me they are directing my call to the relevant department I don`t know whether it`s their strategy to delay the process so that i can get extra charges as by law I am allowed to cancel the loan agreement within 5 days I app**** online and now I am being told I have to go to the branch Standard Bank shouldn`t offer an online service that requires one to go physically to the branch when they have to cancel a loan agreement there should be processes in place to cater for cancellations. The branch that is close to me is always full and taking into account that it is month-end and Black friday week/end I wouldn`t get help as the line starts from outside I only have a few days to cancel this policy and I should be allowed to cancel it online or telephonically as the agreement didn`t take place at a physical branch.
