Credit record and ITC record

<br> I am currently buying a house and i noticed that Miway updated my credit record as: I missed 2 of my installments for September 2015 and November 2015 and in October i cancelled my insurance, because i found a cheaper one elsewhere then only paid in December 2015. This is looking very bad on my profile and i have been phoning for assistance, all i get is, we will update your ITC but until this day nothing has been done. This is really looking bad on my side and for someone who hasn't missed a single installment or payment it is unfair. the agents keep me on hold for 30min if i ask them to ensure it's updated and no one is able to assist
