Moving to a Dark store has ruined my experience

I love the app and I have been using Sixty60 almost exclusively for years to buy my groceries. We have just been moved to a dark store to service our area and it’s terrible, they rarely have much stock and many items I used to order are just ‘not ranged’, these are not seasonal items. I have complained multiple times but they keep saying they can’t change me to another store. I have decided it’s not longer worth me using checkers and then supplementing the items I can’t buy from them, somewhere else. I have cancelled my extra savings plan and will only start using them again once they are able to stock the items I need again. They have caused me such a hassle, having to cart 3 kids on holiday to pick n pay to buy milk and bread because they can’t even stock the basics!
