I think you'll have to wait for a response from the support and either they'll either process your reload or return your BTC back, there is another Bitcoin refill service Bitrefill you can try to see if it works in your location and afaik they use bitpay instead of coinbase so they shouldn't have that round of problem the coinbase seem to be having above.
Bitmoby is better.
Bitrefill and Bitmoby charge More fees than Piiko, This site getting only 2-3%. They also have thread here, and their Support is also very fast.
Well you can say support fast maybe because of your timezone . I got reply from support after 2 hours or maybe 1
