Useless service

Had an account with truworths I spoke to an agent in payments department then requested to speak to a manager, the so called manager assisted me whos coloured as per accent , when enquiring for a clearance or statement showing i paid the account she said I owe the debtors an amount because my account was handed over, since when do clients by debt collectors? I have done debt collections before shes working in Cape town probably with non expertise, in collections or liasing with customers , I will continue to leave negative reviews - the salaries are on time but not the customer service , pathetic service given by Tamrin/Tamlyn whatever her name is , I have then contacted the debt collectors telephoncially and via WhatsApp they not able to pick up on system that I owe anything, how in the hell can I as a customer ow RL Daly incorporated when I owed truworths , why do I owe truworths and RL Daly is this truworths way of getting more money out of us as clients I also spoke to Kholisa at campus square Melville, she said she was going to revert back yet she didnt - this service is so low they can milk a pregnant snake , im utterly disappointed
