i'm almost certain that it's primetrust to blame. you can reach out to them directly for support as strike's support is horrendous and you'll likely never get a response from them.
this is the exact situation i'm talking about here. have you tried buying from another primetrust exchange? you're probably frozen there too.
take this as a lesson and start buying p2p kyc-free instead. stack into a new wallet not associated with your kyc'd transactions. it's a new day in your bitcoin journey, friend. followed. ๐ค
