Antilog Vacations — greece package taxi not provided

The taxi which was supposed to pick us from athens airport to our hotel on 9th august never showed up.. We had to pay 45 eur for the taxi that we hired

Also, the taxi which was supposed to pick us up from athens port to athens airport on 15th august never showed up.. We had to again pay 55 eur for the taxi

I have been following up since last week but keep receiving response that your back end team is working on it

I am asking antilog to reimburse the 100eur which i had to pay from my own pocket..
The driver messaged me on 16th august asking for my arrivals and ferry details which clearly shows that the driver never arrived for the pickup as planned

Antilog is asking me to submit the taxi bills.. Knowing very clearly (Considering they claim to be a very resposnible and knowledgeble travel agency) no receipts are provided by the taxis in greece
