poor service

my husband cancelled debt review by African debt advisors and till this day this matter is still pending. an amount of R300 was paid on 23/08/2017 yet on the 28/08/2017 the accounts were blocked .3 weeks later after making numerous calls speaking to different people only did we receive the 17.W form and after doing that and giving a written letter saying that he wants to cancel he still remains on review. last year when we was in arreas no such company called and yet when no when all is up to date they call.my husband has never missed a payment nor paid late on this debit orders and only 2 chain stores acc do we pay cash, can he be forced to be under review against is will. do we need to take this matter to court. his acc are up to date so why do they want him to be under review he asked to cancel because he was mislead. please advise do we need legal advise this cannot happen against his will.
