Feedback on my account

Good day I am very disappointment now i am a long term client and believe me when i joined the lady attended to my case was AWSOME but thru the years the lady changed or left. now i am at the end of my payments i suddenly have to deal with a account one of my accounts that is more then when i started with Debt Busters the lady in charge of this did nothing from March of which i logged a query till 17/04/2018 (shocking) i can never get hold of her and i have to wait +/- 30 to 45 min for an answer when i phone in for a update. I never had to battle like this with the previous lady dealing with my case. Debt busters was a great help to me and i am highly great full for the service i got from them for the assistance they gave me. But please this is now month 2 that i will be debited for something i have no communication on or result should i stop my debit order at my bank to get a result or what is the option.
