Homechoice harasses me!

Home choice people phone me every day... All hours... I'm so sick of it. I asked one of them to please unsubscribe me. She did and I received an sms saying I'm unsubscribed. That same day someone phoned me again. I emailed them to stop. I tried getting somewhere on the website... No luck. I dont owe them money. I bought curtains a year ago and the nightmare started! Im scared that they might start knocking on my door! (not really...) This is against the POPI act. Not only that... It's harassment!
