Disgusted by service received from Woolworths

Woolworth's financial system blocked my card. I have called them 6 times to unblock it. They haven't done it. They promised me 2 call backs. That didn't happen. I went to Woolworths personally. They called their financial services and they kept me on hold for over 45 minutes. The call center people who I suspect are based in Cape Town sound unprofessional and RUDE. It's like they've never been trained. I'm disgusted by the service I've received from Woolworths and wish I never took out a card with them. Your service is revolting!!!! I pay my account on time and in full. You should treat people better!!!
