Unable to make calls while have airtime

It's me again with the complaint, i logged the complaint few weeks back and the issue was resolved few minutes after that i had another issue and since then, I have been trying to reach Vodacom customer but with no Luck. I have tried to reach them with so many platforms via email,whatsApp and even calling non stop but to no avail.I am now coming to you to help me with my issue as it seems like in order to be assisted by Vodacom i must log a complaint here.

I have airtime on my phone but when trying to call, I am unable to due to insufficient fund.This morning i have run out of Data but unable to buy it due to the issue at hand. I have explained on the emails that i have been sending requesting a call back after 17h00 as i am working in a call center environment.

All i am asking for is for someone to call me and resolve the issue i have of not being able to make call whereas i have airtime. what Vodacom is doing to me is draining and I am so ****ed with Vodacom.
