eDreams my worst nightmare

I booked a return flight from Cape Town to Nairobi in June. From previous experience with a different booking service I paid the cancellation fee in case anything happened and I had to cancel. Something happened with my schedule that I had to cancel my flight last minute, luckily I had paid so I was safe from losing my refund... Right? Well little did I know that eDreams is more like eBadDreams aka eNightmares, because they have a call centre in India, so if you call you deal with a call centre agent that is hearing your case for the first time, I have call them every month since June, it's October now and they all say the same thing, "We will refund you within 48 - 72 hours". They have no integrity or urgency. I have received emails from a "no-reply" address requesting me to send my banking details. How can I do that if there isn't an email or a form to fill in with such details?! I have had no progress at all with my refund, just the same script and email response and honestly rating needs to be in the negative because the level of unprofessionalism is really pathetic. Anything they say on email or call means nothing. There is such a ******** level of operations, I don't even know how to deal with them than to take to the public.
