i want to settle an account but the company doesnt want to give a detailed statement

good day, i have an account with truworths since i was not paying it properly it was handed over to MBD. i took a decision to pay the account, MBD will usually call me and remind me about the monthly payment. i paid on a monthly basis at trustworth. i even requested MBD not to call me anymore since i was paying monthly, knowing that they also charge me for those calls. all along i was paying at trustworth stores, my balance was 260 which i paid. the next thing when i call MBD requesting for settlement letter i was told i still owe them R490 but at truworthy i currently owe nothing. when i asked what was it for, i was told that its for the charges i was not supposed to pay at the truworths shop i was supposed to pay MBD directly but every month they reminded me to pay but did not advice me to pay MBD. Now i've called three times requesting for a detailed statement from the day the account was handed over to them. i even took an effort to send them an email two times requesting the statement, NO FEEDBACK NO RESPONSE. this is really affecting my credit rating. I know my rights this clause also applies to "If a debt collector refuses to send you copies of loan documents or statements for an alleged debt, you have the right to complain to the Debt Collectors Council. You are also entitled to refuse to pay anything until they give you details in writing and supporting documents to their claim". the last time i called them it was no longer R490 now its R540. I hope Hellopeter team will assist me in this regard!! Regards Harold Lebese ********** 993 my email ********** / **********
