Poor Vodacom coverage and customer care.

We have a Vodacom contract but zero coverage at our home. Vodacom installed a booster aerial for us which is now broken. We have reported this on numerous occasions with no response. This week we again reported it but received a message to say they hope we are happy with the customer care but our query has been closed. When we asked why it was closed, we were told we didn't respond to their call! Well that is the whole point! WE HAVE NO COVERAGE so cannot receive calls!! We have now received our second reference number this week but do not hold out much hope of receiving actual assistance from Vodacom Customer Care. We live in a remote rural area with no landlines and no cell phone coverage, we are isolated and at risk.
