12%. Same as cimb card

Guys I suspect shopback miscalculated my order cashback

This is my order :
And this is my cashback :

based on my calculations,I should be getting : 
1. 9% x RM 138.00 = RM12.42 for OVEN (Non Electronic)
2. 9% x RM 290.00 = RM26.10 for STOVE (Non Electronic)
3. 9% x RM 498.00 = RM44.82 for HOOD (Non Electronic)
4. 9% x RM 979.90 = RM88.11 for AIRCON (Non Electronic? I think la)
5. 2% x RM1099.00 = RM21.98 for TV (Electronic)

Thank you to anyone who's willing to help. Thanks
