Old mutual

Not satisfied with the treatment I got from old mutual. I have skipped August payment, then consultant called I have explained why, but she didn't understand. She kept calling during the month, i end up blocking her. So today at 10am 29/8/2025 in the morning she came to my workplace with her branch manager to demand a payment, telling me they will garnish or sends summons to force me to pay. I work as a cleaner, they find me cleaning and they didn't care or asked my line manager to call me on a side to talk with me, they caused commotion, embarrassing me in front of my colleagues and customers. I want to know is this how Old mutual suppose to treat their customers? Shouldn't I deal with their legal team? I felt bul**** and my rights being disregarded.I know I owe old mutual and i should pay my loan but I will make arrangements to pay it Do I owe a company or loansharks?
