Very bad social information toward costumer servive

I saw on Instagram that 50% everything until the 26th , Yesterday i went there it was full and i decide to go today 8:30 and to find out it finish yesterday night . today no more 50% off . why did they mislead their customers on such false information .

That Legit is in Simmons Johannesburg cbd and the store manager is Tryphina .i am so disappointed how could they just end everything over night .
