Extreme baggage costs

Shocking baggage charges. I was given 2 bags going to Dublin from Johannesburg but only 1 coming back to Johannesburg. They then charged 180 Euro per bag to bring it back. So what was I suppose to do with the extra bag that I originally took. To top it off they accepted a 5kg hand luggage bag for free to every single passenger not just us. The plane going back on both legs from Dublin to Johannesburg was quite empty with many many open seats. I will NEVER EVER fly with them again and I will never recommend them to anyone. My husband and I had to pay over R7500 to being our 2 additional bags back what a *******. Unbelievable. Shocking shocking shocking. Don’t ever use Egypt Air ever.
