REFUND STILL NOT PAID AFTER 8 LONG WEEKS

I booked 2 tickets for my kids to fly to George in December. Due to the fact that the airline was grounded we had to make alternative arrangements, and I requested a refund. I requested a refund on 21 December 2018 from Travelstart as I booked through them and was advised that they will need to do the refund back to me.

8 weeks has passed with not refund. This is totally unexceptable as I had to immediately pay to secure the seats but after the airline got grounded that is not my fault I need to beg for my money back.
