******* credit allocating behaviour

I am beyond disgusted at the credit practice of TFG. they automatically increase credit available in my account without my permission. this is wrong and against the National Credit Act. . what happens if someone start spending over their affordability initially signed for? This is the same company that calls you at every hour of the day if you miss 1 payment. i had this unfortunate experience when I lost my job for 3 months. I was harassed. my answer was the same and no one 'cared' . history of good payment actions were ignored. now that i have found my rhythm again I am imposed with additional credit. take is back. I don't want it and I DIDNOT ask for it. stop breaking the law meant to protect us.
