No account with HomeChoice but received Payment calls

Hi ********** Today, my parents received SMS's, still about the same matter; quoted below, which is what I wrote to you already. HomeChoice needs to sort this out, ASAP. This is very irritating.

"My mom has no account with homechoice, yet they continuously call her to make payments. An email was sent to ********** telling them she has no account and that they should stop calling her. Included in that message was an Affidavit from SAPS. This is after she told them several times over the phone. I received no response and they continue to call her."
