You are abusing my Mother!

I am writing this on Behalf of my Mother, a single woman who cares so much about her assets, she has covered almost everything with 1st for woman, from hand bag, car, house and many more.

With all that she has covered with this guys, they still take her for granted, they do not value her as a good client, they take advantage and when she calls they just blow her off, they promise to call her back but they never do!

1st time they over debited her, she called them and they just said sorry we forgot to inform you of the premium change.

2nd month it went up again , she called and was then transferred to a manager (Mthandazo or nomthandazo) , they promised to call back, 30 days later they have not yet called back.

3rd month , they have now taken more again +R400. what now ? will it keep on increasing each month?

how can a premium increase 3 times in a row without a consent from the client?
