No signal from Vodacom - unable to contact them due to no signal

For weeks now I have had no signal from Vodacom. I reported in the past and it was fixed, now it is so bad I get the message "Emergency Calls Only".. When you go on line the request is to call 082135 - how do I do this when I can't make calls? There needs to be another mechanism to contact Vodacom without having to complain. This issue needs to be resolved once and for all. It is not just me but everyone in our complex who is on Vodacom.
