Poor Customer service

Bought a bottle of Green fig preserve and it was disgusting. Never had to chew a rubber fig before. I contacted customer service on the 11 January and spent about 10 minutes on the phone explaining and giving them info of the product. This was the response. "We will be sending you a refund card of R100.00 via SMS to *** within 4 working days". On the 19th January, I had sent a mail to remind them of the 4 working days, which was now 6 working days later. This was there response "Thank you for contacting the Woolworths Customer Service Centre An agent will be in touch with you shortly to provide assistance". It is now the 22nd January and still no response, which is very sad as I have always promoted Woolworth for the good quality food, etc. Needless to say, I am very very disappointed with the customer service. I hope that top management gets to see this and those responsible are dealt with.
