Welcome to the forum.
Are your turtles hatchlings? If so, it's not unusual for the center of the carapace going down the spine to look raised. (If you look at your turtle face on, the overall shape appears triangular.) As your turtle grows and the shells fills out, this will not really be noticeable.
The petstore near you doesn't sell any major brand of pellets (Reptisun, Zoo-Med, Nutra-fin, for example)? Every main brand of pellets that I can think of contains some calcium. If you can find Reptomin Baby (made for small turtles), it has a bit more calcium than regular Reptomin. Then you can supplement the diet with cuttlebone. If you can get him to nibble on a leafy green like dandelions, he'll get some calcium as well.
Aside from a varied and balanced diet, make sure he has proper lighting to bask under (a UVB light and a heat light). He needs UVB rays to provide Vit D3, which helps him absorb the calcium in his diet.
