Disgusting customer service

I sadly do not have time to do grocery shopping and make use of Woolworth on line for weekly groceries. I have been a loyal customer of woolworths for 15 years and made use of their on line shopping for 4 years and spend a fair amount on groceries on a weekly basis. Last week my order was messed up, I called immediately to report the issue. The store or driver didn’t have the same story yet Woolworths said they would need to investigate my claim, if I was so desperate to lie about what I had ordered why on my delivery form did I say the goods were not delivered? I called the call center over 10 times over the next few days which was not helpful at all, I asked to speak to a manager who was never available and email and still have not received a reply for over a week. Products are great, customer service is disgusting to say the least. Are you doing so well to lose a great customer like myself?
