Clearance Certificate ignored

My husband and I were under debt review and paid up all our accounts in September 2014. We were sent a paid up letter by all our debtors and a clearance certificate was issued. I have sent this as has debt therapy but I can still not get credit as my name has not been cleared! The is the case with my husband as well. I was not even able to place my child in the preferred school this year as my credit has not been cleared! This has totally disrupted our lives and we have paid back every cent but can still not get credit!!! Why have our names not been cleared?????<br>
