Ripple balance is shown 0 in ripple wallet through Ledger Nano S

Dear Sir,

I purchased ledger Nano S, from Amazon. (Invoice attached) in February 2018, and I stored ripple into it, I tried to check my balance on 17th of September, but balance shown is Zero.

I restored my Device , and updated firmware with latest version available with you. I installed XRP wallet again, but result is same (balance is Zero)

Earlier, I installed Ripple app, and stored Ripple into it In February 2018

I restored my Device , and updated firmware with latest version available with you. I installed XRP wallet as Ripple device is not available for installation on 18th of September, but I am afraid, no efforts of mine worked. Please help me. I used different machine(computer) for the same , but result is zero.

I expect a solution by your technical team with great confidence.

Thanks & regards!
