Standard Bank Take Me Home service non-existent

I am a Standard Bank account holder. One of the supposed perks ([paid for with my banking fees) the bank offers is a transport service called Take Me Home, which is supposed to deter driving under the influence of alcohol. I have used the service in the past with success, but on Friday 26 July the number for the service, ***, was simply engaged the entire day. I phoned Standard Bank's general customer care line to complain, but I was referred to the vehicle department, which at that time had closed for the day. I phoned the Take Me Home service again today (Saturday 27 July) to check if it has come online in the meantime, but the number is still engaged. No explanation, terrible service!
