Poor support from Helpline

Yesterday I placed a bet in kenilworth via my hollywood bets account. I mistakenly put in R120 on a quartet bed. I immediately tried to contact your help line on *** and they gave me the various options which doesn’t work as soon as you put in the selected option the phone goes off. I phoned again like 6 times and held on for nearly 20 minutes where the voice on the machine kept on saying that I will be assisted within 5 minutes after an eternity I was told that I am nr 15 in the queue and will be assisted within 2 minutes and then??? The phone went down AGAIN!! I then phoned your branch in brakpan and they took my details saying they will also try on my behalf needless to say no response from your offices. How do one correct or cancel a human finger error if no one is able to assist you or reluctant to assist.
