Cannot stop SMS to my phone

Please stop ALL SMS messages to my phone.

You keep changing the sending number so I cannot block you.

Just now I got another SMS from the Pet Club

Your Whatsapp number does not understand how to stop SMS marketing.

Your website does not allow my to turn off SMS.

Your SMS says I must call your phone number.

I am very busy why can I not disable SMS.

This must be against the POPIA law!

STOP SENDING ME SMS
