My Top Tour se niega a pagar el reembolso prometido

Dear Sirs and Madam: I am contacting you because you refuse to pay me the 50% refund you promised on December 30th 2024 because 'My Top Tour' couldn't offer the full tour I initially booked on December 29th 2024: "we can offer you 1. Alhambra night visit on 3th and 50% refund (you will visit Nasrid Palace and Carlos V Palace with english guided tour) ...." Find attached the complete WhatsApp message threads on both of your company mobile phone numbers. I REQUEST My Top Tour TO PAY ME THE REFUND OF € 69,99 + COSTS OF € 20,- I MADE DUE TO YOUR REFUSAL. Regards, K.J. Hammer
