Someone is using my email from old account

Hello everybody,

I have been an expat in Canada (Québec) until May 2022 and I’ve had a Koodo account until December 2021. I canceled my account shortly after.

Now, for some strange reason I started receiving e-mails at the same address I used to register on Koodo in the name of a fellow named Richard Lafontaine, who would have recently registered on Koodo. I keep getting newsletters, information about the service, the last email I received was an invoice for $152. Since I don't have any Canadian cards that I registered in the old account, it is virtually impossible for them to steal money from me. However, I wonder what is going on. Is an attempt at identity theft taking place? How is it possible that I am receiving emails to an address I deleted 10 months ago?
I need help as soon as possible, thank you

If you saw someone used your email to register to Koodo, that person might enter the wrong email when he/she ordered service from Koodo. 

It this is the case, I think just let it be. Whoever made the mistake should realize it and fix themselves.
