Refund

I had purchased tickets on Nutickets in October 2017 sometime for the Corona Sunset festival which had taken place on 16 December 2017, however the festival was cancelled on the day due to bad weather which i completely understand. I received an sms on the day of the event with a link that took me to a form i needed to fill out for the refund to be processed which i thought was absolutely ridiculous, i got no feedback from this even after posting on their Facebook page a month later, and still i received no feedback. I then inboxed them days after my post since no one on the page even had the decency to respond to me, the Admin gave me an email address for me to mail my query to. I received a screenshot showing me that my refund was processed on 28 December 2018, I have still not received my refund and it has been OVER a month since the event, it was said that it would take up to 7-14 working days to reflect after the event (I purchased these tickets via credit card). I have not received any feedback since. I am not the only person still waiting on their refund or feedback as to why nothing has been done, people are still posting up till today. After going through so many means of contacting different people and being sent back and fourth I am disgusted by the unprofessionalism of this organization and seriously considering taking LEGAL action.
