VODACOM NO SIGNAL

Vodacom signal is absolutely disgusting. I have been reporting the poor vodacom signal for weeks now. Had to make a call 8 times last night to finish a short conversation , NOT ACCEPTABLE, TODAY WE HAVE NO RECEPTION WHEN TRYING TO MAKE A CALL, I get messages of missed calls without the phone ringing. Vodacom called me today to follow up my reception the signal was so poor they were not able to have a conversation with me. Their excuse last week was load shedding we are current not having load shedding. all my communication is via Vodacom we are cut of for from the outside world. HOW ARE WE SUPPOSED TO DO BUSINESS WITH VODACOM BUSINESS THIS IS UNACCEPTABLE
