Being incorrectly charged

Received 3 sms's stating my voluntary call limit has been exceeded and then that the phone Is now soft locked. My data was switched off the entire evening. I went on my Vodacom App and saw that my bill was R299. I then phoned Vodacom Data department where they informed me that They have been sending out incorrect smses to various clients and i should not be worried as i still have 75% left, I went to sleep, woke up went about my day with cellular data off, checked just now and was R323 without using the phone at all. I phoned Vodacom Accounts department and when the call finally gets put through, it rang once and was cut off. This happened three times. I then phoned data dept and they finally put me through to accounts where everything I said was loudly echoing back into my ear. I then found myself at client services, so was put through the wrong department. Finally got to accoutns and was informed that they need to do a service request and investigation, but they closed two minutes ago. Now I have to wait till Monday when they might phone me back. I am sick and tired of this bad service, being charged for not even using my phone and then getting soft locked and over charged!<br>
