Vodacom Bandwidth and App a total disaster in Kosi Bay

The Service from Vodacom is crumbling with limited bandwidth and quite often Zero Bandwidth with their routers down especially in Load shedding as they do not have battery backup in the Kosi Bay Region (Kosi Bay Lodge tower). I have also been trying to limit my out of data limit to stop them using all my airtime and am unable to set the limit getting errors when trying. Received that limit was finally set SMS's but they still took all my airtime when data ran out! Also having to use USSD *111# to monitor usage as their App often does not work hanging.. when using the USSD codes they send you a SMS to use their App!!! which is not working why I am having to use USSD codes! Absolutely Hopeless ..
