Billed R1900.23 for a phone that was off

So on the 14th February I went away for valentines day. Due to the location of the game resort there was limited or no signal. <br> <br> Then all of a sudden i get a data account for the that day of R1900.23<br> 2,485,088.07 KB internet 35 R 1,900.23 14/02/2015 00.20<br> <br> When I called customer care I was put on hold about 5 times over a period of 30min. Then been told the exact same thing over and over, can we email you your itemised bill, which I have been looking at all morning while on the phone to, accounts, customer care and data services. NO ONE listened to the question I posed. How did I get this account when 1) Phone was off, 2) there was no signal. I is a platen misuse and abuse of service offered by vodacom,
