Panasonic — storage and SIM slot problem

I have bought the phone Panasonic eluga S few months ago. I have no serious issues with it but certain problem occurred that is when I bought it and tried to insert the two sims, one slot is not working in which W is written.and the another problem that usually occurs is that whenever I download any app, in settings there does not appear any option to shift the specific app to the Micro SD card.please see to this problem urgently. We have tried to call Panasonic care services but they don't even bother to pick up the phone.please see to it.
