Disappeared Data/ poor customer care!!!!

I called the Vodacom customer care line this afternoon and spoke to a guy called Vusi who wasn’t listening and didn’t even try to assist me with my issue. Over 5GB disappeared in less than 30min. For some weird reason I got multiple Vodacom sms’s at one go on the balance of my data when I didn’t have anything unusual turned on, on my device. He insisted that there was usage regardless of my explanation that there’s nothing on, I’m annoyed by the lack of investigation and poor customer care. Vodacom I want my data!!!! Communicate if there’s an issue. Those sms’s were a sign that something is wrong!!! I want my data!!!!
