Horrible service from Travelstart. They dont pay refunds

I paid for cancelled flight ZAO*** on the 26 February 2021 as on the my travel stat profile flight showed pending and not "cancelled" I was desperate for the time slot so paid and went to the airport in the morning -Airlink told me that the flight was cancelled I should request refund from the agency i.e Travestart. the frustration started , you call the line and you reach an answering machine. no one to assist but you will be reffered to a whatsapp which gives you irrelevant options to choose from. you email, no one responds. even after sending the information they need they will not send a confirmation that they have received your details. I sent my proof of payment and banking details on 02/03/2021 my last resort was going to their facebook, on monday, a lady confirmed my banking details and proof of payment have been received and i should expect refund 3-5 days. Today is the 5th day since that confirmation and no refund received. The amount due to me is R2924.00

They deserve half a star or no star at all. their service is horrible
