miningbuddys - Product Dont deliver after raising the price

So my complain against https://miningbuddys.com/
What happened is i place a order of a Asic Miner worth of ** Lak ** Thousand around and i paid half like *.*L in sep **** and the promise to deliver within by ** days so what happened is that Asic Miner Coin value increase and the in global market the miner price also increase by double triple, so i dont think if i got a invoice of the **,*****, why should pay more if price increase or decrease i dont care about that. But the https://miningbuddys.com/ refuse to send the miner and they always say to refund but i waited * Month for it and they said take the money and a btc miner instead while your ordered miner got clearance from custom as they said before. So i took the refund but they did not send the btc miner as agreed also they refuse that agreement also. I ordered Goldshell KD* miner and now its price on their website is **L around but i ordered for **.*L thats why they did not send me the miner and they harsh me a lot. So please i just want my Goldshell KD* Miner i agreed to pay full amount as i did before. They just trick me, i can also complain a police case but i found you guys, hope you will solve my problem
