Lack of service

I sent Woolworths a query about 2 of their food products on 19th April. I got a response on the 20th where I was asked for my email address or phone number. I supp**** that. They responded on the 23rd and said they would follow up. I heard nothing. I followed up on the 27th to which they said they would follow up. To day I have had no feedback. This is disgusting service indeed. I have not received any answers to my queries. Shocking for such a large company.
