Mytrip refuse to grant a refund, Skyscanner and Emirates refuse to advocate for their customers

If I could give them zero stars I would, one star seems far too generous. They changed one of my flights to an unsuitable time, so I requested a refund. This was in June. Today is the 5th September and I still have no word on when my refund will come through. I call their (unfriendly) call centre every 2 days or so, but no one will give me any information. This money equates to more than a months salary for me and their refusal to provide a refund has left me struggling to pay rent and other monthly bills. I'd also like to mention that Skyscanner happily advertises Mytrip, which is the reason I will NEVER use Skyscanner again. Emirates have been equally unhelpful, not even willing to offer any advice, rather adopting a "not our problem" outlook on things.
