Unnecessary Enquiries on my credit profile via transunion

I have been with the insurer for almost a year, today I received a message from Transunion on an enquiry made by your company and I fail to understand while all of a sudden you’d make an enquiry on my credit when I have active insurance with you people. I am disgusted and disappointed with you ,these unnecessary Enquiries are reflecting badly on my name. My creditI score was sitting at 61% and went down to 58% . As a company you should know when you do a credit enquiry on a customer that information goes to credit bureau and it’s a negative reflection on my name. I am trying so hard to improve my credit but you people are tarnishing my credit scoring that I’ve been working so hard to improve. I want you people to contact Transunion and rectify this error or else I will write to consumer Ombudsman and also take my business elsewhere you can’t play with my credit score

I need an urgent response from you people
