Terrible customer service and signal

I've had it with vodacom. This is the 3rd time in two days that the HOSPITAL cannot get a hold of me because my phone doesn't have signal. I tried to phone customer care (*** ever, they dont know how to take care of customers!!!), to report the signal problem. But I was bluntly told by dearest Thabo, that he cannot assist me because I can't answer all of his 10 security questions correctly!!!!!! Just because I cant remember which package I'm on (what diff does the package I'm on make to the fact that I dont have signal???). So I'd just like to publicly tell Vodacom to go.to hell!!!! You're the worst network EVER!!! It doesn't matter who I am, and how much freaking money you take off my account each month, I needed you to be reliable so I can get the critical call I've been waiting for, not being told you can't assist me ?!?! Thanks for making my day EVEN WORSE, and please... take your contract and shove it where the sun don't shine!!!!!!!!!!!
