My store currency changed from EUR to HKD

I visited Hong Kong a couple of months ago, I only used my smartphone to log into WT Mobile and never bought anything there. Now on my PC back in the EU where I live all store prices are in HK Dollars, how do I revert back to my home currency EUR in which I always buy things?

If logging into wt mobile changed it once, try it again i guess🤷🏻‍♂️

I log into WT Mobile daily here back in the EU, it changes nothing.

When you get to the final checkout page, towards the upper right side of the webpage, you will see the price and a drop down menu allowing you to change the currency to your liking. Then you can pay, no problem. Trial and error goes a long way.
