Flase advertising on Lipton Rooibos tea box it says 80 bags

Lipton please explain why your Rooibos tea is advertised as 80 teabags, but there's only 60 in the box. I though if this was just an honest mistake whilst it was packaged, but when i mentioned it to my mother-in-law who buys your tea religiously she said there's always 3 packs in the box which i pointed out to her ofcourse equals to 20 bags per pack. I want answers?? This is not on you are robbing us of 20 bags as per the 80 bags printed on your Lipton Rooibos tea box.
