Supabets horrible service

On the 22 February 2019 I transferred money into my Supabets Online Account via I-pay, that was R1000 in total but the Amount transferred duplicated and R2000 went out of my Capitec Account instead of R1000. Supabets only allocated R1000, I enquired with them. They asked me to send proof reflecting the BR number, I did send multiple times on their Whatsapp number. I made multiple follow up calls and they kept on saying the Deposit Department said they were going to allocate the R1000 before the end of the day everyday but they never did, when asking them via the Whatsapp number they kept on asking how they can help me and when I respond they are now ignoring the message. Spoke to multiple consultants and to date I still haven't received the R1000 they owe me even though they have received and confirmed all the transactions proof they requested. They are able to view my query with all the proof on Whatsapp but they refusing to pay my R1000.
