Frustrated : Want to make a Payment arrangement

I just found out that I have an outstanding amount with Vodacom and I am trying to make payment and future payment arrangements but I keep getting passed from pillar to post for the last 7 days. I have made use of Tobi and i love the bot but when connecting with a live consultant, i was advised that the number i am calling was the only number available. I have told the consultant that when I dial the number last week it said that the service is unavailable and told me to try again later and I also told the advisor that when I called *** today, I was met with a greeting but then placed in a loop. I was then advised by the consultant to do the following

"Sisanda Bayanda Khwezi: ***4 or please contact this number and askthem to transfer you"

I did this but was placed in a loop again.

I just want to speak to somebody, make a payment and then make a payment arrangement. Or chat with someone who can be a bit more helpful even if it's via email?
