Did not receive my full orde, misleading promotions but your prices increase so many times in 1 year. Pathetic service

No response received from you after I sent an email on 22 April 2022,my order was wrong and when I notified you you never responded. You sent a promotion of Muesli yogurt delight 1kg,if you buya case, you get 1 case for free. I ordered a case and I only received 1 extra back, instead of a case. No one ever called me after I notified and returned a signed invoice with a note. Lack of service it's pathetic really. The service levels are dropping by a day
