incorrect information leads to over paying

i was told by customer care when i got my new samsung neo that i can still load and use bbm on my phone but i must still pay the R57 for BIS so i did, just to realize that my bbm only work when connected to wifi and not connecting if out of wifi range. i phoned customer care countless times just to get sms'es of steps to follow. it has been almost a year now and to my suprise i phoned them again and they told me that BIS does not work on a samsung phone. SO WHY DID I PAY R57 EVERY MONTH???!!!! I want my money back then as i could only use bbm when i had wifi connection and Incorrect information was given to me. Very Very dissapointed. Does it take a year of wasting my money before i can get the right info!! WANT A REFUND ON THAT MONEY!!
