Pathetic Lewis stores

Lewis stores put my name on credit bereau for a missed payment and account in arrears when I have NEVER missed a payment as it was on debicheck and my account is actually SETTLED and PAID IN FULL! My homeloan was declined due to this false information. No assistance from head office even though they said the matter is sorted and it's been removed from ITC. No response to my emails asking for feedback! I require urgent assistance!!! I'm not the first person they have done this to according to the branch where I opened this account. They are just putting wrong information and ruining peoples lives that are hard working!!! Pathetic!!!!
