No response

I am in disbelief on eveyone in a company can ignore me...I previously had a contract with Debt busters but decided later on to terminate the contract as I wanted to speed up the payments,I was in contact them and I signed some documents for them to stop debiting my account..but they mentioned that when I have paid up letters I must contact them for a clearance certificate..I have written to at least 3 people none.of them have responded..I then decided to contact the general email ..they responded saying they are allocating my matter..since the 25th September to day no one has contacted me..this is very upsetting as I need to clear my credit record ASAP so I can continue witj my life..everything is on hold because I still have my name flagged ...
