Outsurance bad service

I am very very unhappy with outsurance i cancelled my policy with them in 2017 and the never send confirmation to the credit bureau to have it removed. I logged a dispute with compuscan and the outcome was that they do not get any feedback from outsurance to have it removed. How can a well known company be so terrible at providing proper customer service. I spoke to one of their call centre managers yesterday who want to insinuate that it is my fault that they did not do their job... I called the bureau again this morning ant outsurance still did not send them feedback i am very angry woth this service provider who acts on tv like they the best but suck in real life
