Loss of prepaid data - Tower down (Buffelskloof dam/***)

I am a pre-paid customer on Vodacom and purchased a 3GB and receive 3GB free for 30 days (this was due to expire on the 11th of February). The last 12 days the Vodacom signal in our area was on and off the whole day. We would have at approximately 12 hours of the day without any Vodacom signal. The last three days we had no signal at all, all our devices showed No service for the last three days. The signal just came back and when I looked at my app my data balance shows zero. I feel that I should not be penalized and lose all my data as the problem was my service provider that was down, and I was then unable to use my data before it expired. Our location is 24° 59'00 "S 30° 14'04 "E
