Vodacom Coverage has tanked

I am very irritated with Vodacom's Network coverage and call dropping. I am on a Red Premium plus package and since I have been migrated to the package I have dropped calls (Call Failures) on almost every single call I make, which is annoying, you pay through the roof for a service that Vodacom is clearly not providing or is this your way to tell us to keep the call times to a minimum to save yourselves a buck or two? I also live in the Primrose Germiston area and the last few weeks I have been battling with my data service, WhatsApp just hanging because there is no Network coverage, messages taking over an hour to be delivered or to com through, it is absolutely rediculous and completely unacceptable.
