U.S.-based Mondelez International told CBC News that it stopped making Dad's chocolate chip cookies late last year and that the product dwindled from stores shelves over the following few months.

Other varieties, including the oatmeal chocolate chip version, are still available in Canada — the only country where the Dad's brand is sold.

Mondelez says it dropped the plain chocolate chip cookie due to poor sales.

"Nobody wants to see a brand go, but sometimes we have to make decisions," says Stephanie Cass, corporate affairs spokeswoman for Mondelez Canada.

It's not where you say it is

The news didn't go over well with Susan Armstrong from Langley, B.C. who was a huge fan of the Dad's chocolate chip version.

"I think it's the shortbreadish taste. They were a good tasting cookie."

Following her own unsuccessful quest for the cookie, Armstrong contacted Mondelez earlier this week on Facebook, looking for answers.

On Tuesday, the company messaged her back, insisting the cookies were still available and even offered her a list of stores in her area carrying the product.

Armstrong had just searched one of the stores — Save on Foods — to no avail. So she called the supermarket's head office and discovered that Mondelez had discontinued the cookie.

"I was so angry with them," says Armstrong. "Why wouldn't you just say to the consumer, right off the bat, 'This particular brand of cookie, we're not selling anymore,' instead of prolonging this nonsense about, 'OK, well, you can get the cookie but you just can't find it.'"

Other customers have also expressed frustration with similar messaging from Mondelez which told people the cookies were still available and to use the company's online locator to find a store carrying them in their area.

"The product locator is not accurate," posted Ariana Boire on Facebook earlier this month. "It says the chocolate chip cookies are sold at Walmart and Save on Foods and I've been to both and neither sell it. Where are my favourite cookies!!"
