Rude staff and system not working

if i could give a zero star i would have! i have made an arrangement with ACS Credit Kasturi Haripersad on 25 April @ 15:22 for payment for the next 6 months - kasturi claimed to have updated the arrangement - which was untrue. On 14 May 2025 - i again received rude and threatening calls from ACS Credit . AGAIN on whatsapp Kasthuri Harispersad rudely advised me the arragment was updated. I can explain so many times my situation = and getting threating and rude calls 48 hours after losing a loved one - is unneccesary and uncalled for when Kasthur Harspersad is at fault and not doing her job! fix your Staff and your systems as clearly it is NOT working or doing their Jobs!!!!
