Horrible online service from woolworths

I have recently had a terrible experience with woolworths online. I placed an online order which I canceled at a later stage because the order was late. 1 woolworths promised me a refund I have been waiting for almost 2 months for a refund. I have been calling customer care whereby you hold on for close to 20min before a agent answers. I have lost count as to how many times I have called and tried to get my refund. Emails are just not worth it 4 complain emails and no response to 1 of them. I am really horrified at the service I have been getting from woolworths.
