Corruption

I am very dissapointed by the branch in Johannesburg,A well known company like them doing corruption,We used our last cents to attend the interview only to find out that they already gotten the lady they where looking for,The girl's relative/sister works there so they didn't even interview us but just taught us the system,They never took our Cv or cellphone numbers but they took our names and the lady said we should whatsapp to find out if we made it like really,When we got therein the morning the lady they already hired was so comfortable doing ups and downs in the offices with her sis while we wait at the reception for nothing,We got there before 8am and went home after 1pm claiming to be selling and learning their system,I am angry because I wasted my last cent and cancelled my other interview only for them to be corrupt,Why did they waste our time?So all of us went out after everything and the lady they hired remained to continue working,We really deserve better as youth. We were all angry and dissapointed but what can we do besides talking about it.
