Ibotta isn't as bad as some reviews make it out to be. I've gotten locked out once from ibotta and it was Bc their system flagged me thinking I had redeemed more offers than what my receipt stated. When I contacted ibotta, they did response back to me within 2-3 days and eventually unlocked my account once a review was completed. I've also contacted them several times since then and have gotten back quite professional and helpful responses. I honestly don't think they're just going to lock & terminate your account so they can steal the money.
A tip: if you are going to contact them, try using the app directly instead of their email address. Basically click the bell' icon top right corner when you first open the app. That will list all the activities from your account. Select the first or whichever one you have an issue with. Then click the question mark' icon top right corner then select report an issue' and write from there. They seem to respond to this quicker than sending them an email.
The only time I had an issue where I wasn't credited was Bc the receipt didn't state the brand of product. The store, Sprouts farmers market, is very minimal with their receipt and has no product numbers shown unlike say Walmart. So if Ibotta system doesn't recognize a brand from the receipt then it will likely flag your account. Whenever I scan my receipts from Walmart I always, always get credited accordingly.
So in conclusion, ibotta is a pretty great app to save on groceries. I don't buy everything from ibotta. I only buy what I need or use often especially if the items are on sale as well plus ibotta cash back. Score! Customer service can be slow yes, however very reasonable and helpful whenever I report an issue. And always withdraw as soon as you reach withdrawal limit of $20. Would I recommend Ibotta? Absolutely yes. But I would also explain how to use ibotta as well and don't try to cheat the system.
