Illiterate and *********** ground staff in Cotonou

I was denied boarding by an *********** and illiterate gate agent in Cotonou. The agent could not read English and claimed my visa was not valid. Staff at the check-in counter later admitted that my visa was valid after I had been denied boarding and after I had missed my flight. Ground staff was unwilling to help and issue a new ticket. They referred me to the call centre. The call centre was thoroughly unhelpful and kept me waiting for hours. User's recommendation: Be careful using this airline in jurisdictions, such as Benin, that have limited customer protection.
