没5刀了 买个7.5刀 然后工单换套餐可以吗

应该只能升不能降吧。或者说改年付，PY一下看看咯。

加钱应该就行

可以，客服挺好说话的。

能升级不能降级

没付款前可以，付款之后，没试过

I want to buy a VPS. Can you offer me one at a 50% discount? If it’s an E5 VPS you want then yes. sure.Can you change the price for me? Yes, let me know what hostname and operating system you want along with what billing cycle you want. I created an order, you can change it for me Updated

好像是 不可以换低 只能换高

可以，只要没付款就能改，没付款过期了有时候也能给你再开一单。直接工单中文就行，不用装老外
