Balance Escalating thanks to INCOMPETENCY

This query refers to a ticket that was opened about 35 days ago regarding my balance on an FNB overdraft. I called FNB a while back regarding my balance and to my surprise the balance was close to 50K yet when I joined debt busters in 2018 the balance was 33k how am I now owing close to 50K? I enquired this and they advised that the monies that debt busters have been deducting from me has been paid into my savings account and not the overdraft account therefore the overdraft account has been accumulating interest hence this is where I am. Now as a reputable company that's been assisting a lot of people with these types of issues surely you should have known that the payments were supposed to go into the overdraft. Now today I get a statement from Hyphen with a balance of 48K how am I now owing way more than I started with? why can nobody give me answers? apparently you have been waiting for an answer for more than 30 days from FNB. I thought debt busters was supposed to deal with all these nitty gritties now I must run around trying to deal with *********** individuals that cant give me any answers
