MyDifference? More like lazy staff

I have been struggling to register mydifference.... this has been a painful experience as I enjoy shopping at woolworths but their customer service is terrible... I have been back and forth where I have not heard anything for about a month now... is this how you value your customers? Using vouchers at the store helps with saving but clearly you are not interested in fixing the problem as long as I spend money in your store. I will not be using my account anymore
