Supabets

I have been with online supabets for a long time but they behave like ****** now.. I deposited 300 zar in their account on the 26th of November 2019 and it didn't show in my online account I then contacted the deposit team via email and they didn't respond to my emails I then contacted suport they asked for proof I went to standard bank and they gave me proof I sent it to them they said they apologize they will attend to my problem and they didn't today it's the 29 I sent proof again they said apologies for the delay and still my account hasn't been credited I m so disappointed I would understand if it was money I had won but it's not its money I have worked for and I want it back
