POPIA ACT BREACH!!!

I took back a product a while back due to it not fitting in my space. This required me to write down my cellphone number, for RETURNING TRANSACTIONS purposes.

Now they keep calling me to open an account with them. This is a CLEAR violation of the POPIA act! They call me numerous times a day. I am now fed up. They are using my phone number for different reasons than it is intended for. I am utterly upset. I have asked them to remove my name, but still not! I DID NOT CONSENT.
