Woolworths Bad Service

I recently received a Woolworths Credit Card and when I tried to use it recently,I received an error message as card is blocked and I needed to call wfs to unblock card,I have been calling Woolworths since last Friday the 2nd of September and my issue is still not resolved,I then called again this morning the 5th of September and I was advised to send through a copy of my id as my credit card was blocked as the suspected *****,that was sent and I received a call from an agent named Tanya saying that my card is now unblocked,I then tried to use my card but it is still blocked.I have been trying over and over for several hours now and no one seems to be able to assist me as no one knows the reason why my card is still blocked.It has actually appalling that an institution like Woolworths has the worst customer service that I have ever experienced,really sad.
