We were originally with Simple Debt Soulution but our IVA transferred over to Creditfix and had nothing but problems in the final year and still ongoing problems. After a year and a bit of our IVA been complete we went to buy the rest of our house as we were part buy part rent. The debt was still showing on our files so work had to be done to remove the debts, the paperwork to remove the restriction on our house was not completed so our solicitors had to work hard to get the RX4 form complete.
Three years on we are still having problems. My partner had a letter from a company saying interest rates had been worked out incorrectly so a cheque had been sent to Creditfix, three months on are we are still trying to get this money paid to us and are experiencing really poor customer service.
