False advertising

I purchased Lions Mane (60 capsules as it was advertised) through their website using the express delivery because I wanted it by the weekend to help me focus on my studying. Very impressed with how fast it got delivered. Opening the box i found that i received a 30 capsule container. I contacted their support team informing them of this mistake and me still expecting the remaining 30 capsules to be given to me as that was what i ordered. They apologized for the inconvenience as that was an error on the website and that they don't have 60 capsule containers. They updated the item on their website but im still left without my item as they will be collecting it and processing a refund. I took a screenshot of what was advertised. Im not working and had funds for this item to help me focus for an exam coming up. The fact that they were so inconsiderate regarding their own false advertising then expecting their customers to take it with a pinch of salt! It's unacceptable.
