Vodacom BAD service - dropping calls

I am so over Vodacom dropping calls - almost every call I've made the las couple of days have been dropped and I had to call again just to finish the conversation - in some cases had to call back 8 times!!! I have 5 Vodacom contracts on my name, and additional Vodacom company phone, my husband has 4 contracts on his name. We are paying way over R5000 per month on this - and for what??? For bad service and reception. As my contracts become due for upgrade from now on I am moving away from Vodacom!!!!!!!!!!!!!!
