Woolworths Insurance claims

The end of last year I suffered a heart attack and had a double bypass. I have dreaded disease cover on my Woolworths Black Credit Card and my instore account for which I was paying R550 a month. I have submitted the required documents 3 times without any feed back except a consultant will contact me in 5 days. Due to this my credit rating has been adversely affected and I receive 3 phone calls a day from their debt collection attorneys. I have spent hours on the phone trying to talk to the right person. I've have asked to speak to senior management with no success. I continuously phone ***and am cut off when I select the various options. This is totally unacceptable and would like this matter to be addressed as a matter of extreme urgency.
