Failing to refund my full amount

Bases on first complaint on the 18 September. My reference from the store recieved was ********** 0618/go. As I can't put my ID number online. I received a call saying I was refunded R712 but that not the full amount, I was told that I can go to the store to get a statement but the store said they can only print for the past 6 months. How will I know they have refunded the full amount? Now I am told that they only refunded one policy yet there where more them two policy added to my account. Seem like jet is taking my money for nothing. I called the call center again and was told by Ayanda that they only refunded one policy because the other ones I signed for them at the store the same day I went to cancel which is strange. She says there is no cancellation at the store which he needs to sign imagine how much money jet is making out of us people who don't get their statement? Seems like all this is a ****.
