Total Incompetence

i started a new job on the 1st of march. my salary date changed thereafter. i called capitec around the 24th of March to change my debit order date and was asked to go to a branch with my new payslip. i went to northgate and for starters the young gentleman doing this did not know where to click and which software to use when doing the changes so another lady had to come help him along. they told me they were done and i asked them why the date showing on screen is not the new date but still the date of old and they told me i must not worry it is linked to my company details and the debit order will go off on the correct date and to my surprise i get an sms notifying me to put funds in my account today which shows that the change of date was not done. THIS will affect my credit score if not fixed by capitec can someone please help
