***** on my profile

HomeChoice keep on doing credit enquiry without my consent which is affecting my credit profile. This is the second time in a month that this is happening, I logged a complaint to their customer service and even their ***** department with no help. Can this be investigated urgently. I can’t even login to my profile as they have changed my details. I was advised that the ******** won’t be able to buy again with my details but that’s not true since they did same thing again this morning
