Limited to no signal in Selcourt, Springs for last three weeks

I have 11 vodacom connected or not connected devises at my address. Have been a customer of vodacom since the mid 90's. for the last three weeks, I have had little or no signal while at home. My devises are in full working order as they function well out of the area. Have contacted Neighbours through local area Facebook page to discover that all have the same problem. Many are change to other service providers as soon as contract expire. Some have been told it was as a result of a storm three weeks ago. Not acceptable service.
