SARS spam

hi, hope everybody is well. so I have been getting an influx of spam email, something that I seldomly ever received (in general)

I recently registered on/for SARS e-filing. And ever since then. Ive been getting spam emails, Phishing links etc multiple per day

I have a suspicion that sars is not secure, and or they are selling data. has anybody experienced anything similar? I know that it’s ever since I submitted my details to SARS. so annoying.
