We bought the round trip flight tickets for five people from Hong Kong to Casablanca with Gotogate on 22 Dec., 2018. We will set off received an email from Gotogate dated 12 May 2019 saying that "there is flights changes, if the new schedule is not suitable for you a full refund of the ticket is also possible (less credit card or internet bank fee)." We were informed to reply to their email within two days. Therefore I made the request to cancel the booking on 13 May 2019. Since we got no reply, I sent the email to ask for them but in vain. I called the customer service twice, their staff told me they would transfer my call to another person, then my phone got cut off. Then we received their another email saying that my original flights are again operating with the minor time change. But we have purchased the round trip flight tickets with other airline. We will set off on 15 June 2019. We sent them emails many times. They ignored my messages. Up till now we haven't yet received their response. We can't get our refund.
