Sending my confidential notifications to my former boss

I have been on paycity for about 10years and for about a year now I'm no longer receiving notifications from them and my former boss last worked with in 2014 is the one receiving my notifications. I tried checking on the website all my details are still correct and I've never changed my number and I've never used her numbers anywhere except on my CV. They said they'll update system but never answered how they have her number as mine . Till to date I'm not receiving anything she is the one receiving confidential notification know my current trips and offences,
