Disgusting service

Terrible service from Jacaranda FM. Jacaranda had a guest on their show (Malcolm X) on Rian's show on 28/06/2018. Callers were asked to call in and whoever gets though will win. Needless to say, i called in and was one of the "lucky" callers. I was told that someone will call me to get my details. Today is 06/07/2018 and as of today, i've had no response from them. Left various messages and emails, no decency to even respond to emails. To say the least i am totally disgusted in them.
