Vodacom lost data

Good day,

Let me start of by saying that I have wifi at home and at work. The only time I am without wifi is when I am on my way to and for home and work. I purchased R149 data bundle, 1 Gig yesterday afternoon only to receive a message now saying that I have been paying for data as I have no active data bundle. Previously I would receive Smses informing me off my data balance and between yesterday and today I have received none. I then called your *********** customer service center only to be told that a technician will get back to in 24 - 48 hours as my phone was connected to the internet the whole time. Your service is ****! That is why I refuse to take any contract with vodacom. So now I must buy another bundle continue paying in airtime as this is probably not your error. Please refund my airtime and data!
