Popular confectionery brands such as KitKat are forever dreaming up ‘limited edition’ variants in order to boost sales.

But when Saima Ahmad opened an eight-pack of KitKats to find that a few of the bars had no wafer inside, she was furious.

The 20-year-old law student from Enfield, north London, drafted a strongly worded letter to manufacturers Nestlé demanding compensation – preferably in the form of a lifetime supply of the inimitable 4-finger bars.

Saima explained: "They go about advertising the unique concept of KitKat, but I'm so disappointed by what I have purchased.”

Saima then revealed that the issue wasn’t an isolated one.

"I have researched this problem and I found that it wasn't just a one-off and it has happened quite a few times,” she added.

"There are quite a few forums online where people complain of having KitKats without wafers."

Saima Ahmed's freak all-chocolate Kitkat

None of the other purchasers who ended up with a solid chocolate KitKat seem to have taken the matter quite as seriously as Saima has, but she’s confident that her demands will be met.

"They should definitely give in to me, I'm hoping my demand will go higher than the customer service platform.

"I'd like the CEO of Nestle to respond to my letter because it's an extremely important issue.

"I'm trying my luck. If you don't ask you don't get."

In her letter to Nestle, Saima indicated that a lifetime supply of KitKats would allow her to act as a quality control for the product:

"The loss I have suffered is of monetary and emotional significance.
"I would like a full refund of the defective pack of KitKat I purchased. I have also lost my faith in Nestle.

"Clearly, if I wanted to purchase a confectionary item that is purely chocolate, I would have purchased a bar of Galaxy.

"I would therefore like to request a lifelong supply of KitKat so that I can act as a means of quality control - it appears you need me more than I need you."
