Sunbet has not credited my account in over 8 hours.

I transferred funds from my personal banking app to Sunbet in the early hours of Saturday 26 August. After a few hours, my Sunbet account was not credited with the funds. I proceeded to email proof of payment to the provided support email address. Hours later no response and my Sunbet account is still not credited. I proceeded to try and call several numbers for the helpline provided, NONE work. I then called Sun International Head Office, and the phone line is not answered. I went further and tried to call central reservations, and a lady by the name of Mary-Anne informed me that she was not able to redirect my call to Sunbet, and provided me with the 0861 number that DOES NOT WORK. I've been waiting over 8 hours and still no response. My frustration is that the activities I would like to conduct are time sensitive and I am unable to get any assistance or feedback from the company. This is not the first time something like this happens. I would either like my Sunbet account to be credited or I would like my money back.
