Mytrip.com complaint: Failed to check in

On 5th of May (less than 24hrs before my flight) I did not had my boarding pass so I called to our customer support where I was advised to that I had to wait 3 hours before my flight to get my boarding pass. However on mytrip app says that it will be available 24 hours before.
On 6th of May (4 hours before my flight) called to customer support where I was greeted by a very rude employee that apparently he was not in the mood to help and hang up the phone without even trying to help. After, I called again to mytrip helpline and a different assistant told me that I had to wait 3 hours before my flight to get my boarding pass, after I told her that my flight was due in 2 hours. So they told me that I had to check in at the airport because they were unable to do it, which I have done and paid about 70 pound.
Please note I tried to check straight through wiz air online but I was not able to.
