Flights Experts

Before final payment, I checked & confirmed the flight details and costs with Flights Expert. They confirmed everything before I paid the balance. One day later they sent me an email saying that the price has increased. I was furious! I have asked them to reimburse my funds but they are instead harassing me with calls and emails to take another totally unsuitable flight - in terms of days and airport etc. They say they are offering me good customer service seemingly impervious to the fact that they have caused tremendous distress as I had very specific plans. What is also annoying is that the price I had paid was already nearly double what the 'offer' price was in the first place. I will never use this Agency again and will book direct myself next time.
