Raw deal

Vodacom billed me R944.11 to do a 1.2GB iOS9 software update even though my wifi router I'm contracted on with them offers me 1GB night owl data and I had data that I had carried over from the previous month. This happened despite having set limits with Vodacom on the said router, that my additional spend shouldn't be more than R50 above my R105 monthly subscription.<br> <br> The update wasn't even successful, due to some error in connection. All my 1GB data of night owl and the carried over data was gone even though the 1,2GB software update failed and on top of that I'm billed R944.11.<br> <br> After querying the invoice and enquiring about the purpose of setting the limits, I was told that the limits are not guaranteed and I'm still liable for the additional charges. Based on my history with Vodacom, 15years all in all, I have never utilised the internet that abnormally. I feel short changed because that goes to show that I'm being billed for what I didn't consume.
