Failure to act on a querie

I app**** for debt review in 2013, bu5 in January 2015 I requested to cancel it voluntarily as it was not working for me, the debt counsellor issued me with the 17.4 for. After 6 months i realised that it still reflects on my credit profile, i wrote to Transunion, it removed the debt review flag on my profile as well as another judgement that i had paid in full. In december 2015 i learned that the debt review flag still appears on compuscan and experia, i wrote to the two credit bureau as well and submitted all documentations. Compuscan responded that the matter would be addressed and that they needed 20 days to do so in January i wrote back to check progress, they also have removed the flag and they furnished me with an updated credit report. However with Experian, the removed the judment only, i made them aware in december that i requested for debt review matter to also be removed, they responded and said the matter is referred to the relevant department. I wrote in again, I made Bulelwa that the matter is still not resolved. I tried to call but there is no answer. Please assist
