WORST ADMIN / ACCOUNTING EVER DEALT WITH!!!!!

I requested invoices from Airport INN and after reminding the lady that she shouldn't forget the dinners, she send me an invoice WITH NO DINNERS. Then she send me second invoices, on which I was OVERcharged for dinners on one of my invoices. Then my employees only received one soft drink each where the invoice clearly stated two per customer per dinner. Then I cancelled my second stay at Airport Inn for which I allready paid, and have sent two e-mails in which I ask for my refund, which should be half of the price of the second booking and the dinners that was overcharged AND THE COLD DRINKS MY EMPLOYEES DID NOT RECEIVE, but I have not even received a reply from the guest house. Our stay was on 11 and 12 May, and today 28 May I still haven't received any word from this guesthouse about my refund. I Won't recommend this guesthouse to anyone.
