Poor communication

I'm underdebt review with ndc. On 11 July SARS deposited money in the account that I closed. When I requested my bank Absa to transfer money to the account that I'm currently using, I was told that I should contact NDC. I then contacted NDC, sent the proof of payment from SARS, sent bank statements but thereafter there was no response. I called the consultant that I usually communicate with and she later sent me an email that it's day 4 of the query, it will take 7-10 days to resolve the matter. The response from ndc regarding this case is not professional at all. I'm the one who has to call now and again, they don't care about giving me the feedback. Sometimes I call and the same consultant will never bother to call you back. Their service is good when they still need you, when you need them, they don't care. I wouldn't advise anyone to use ndc, look for other options to relive your debt
