Accidental LST purchase

Took me until today, from the start of coliseum to earn the 5k era currency to get the LST i wanted, for Tarfull. I was nearing the end of a 12hr nightshift and struggling to stay awake. The next round of coliseum began and I thought, "this will wake me up!"

I collected my rewards, taking me over 5k, had been waiting for this for so long... went to the era store, checked the first LST, looked for Tarfull, nope - he wasn't there, went to exit and tapped "buy" *facepalm 

Please please please! I haven't spent the token! Please devs, can you help me and take that LST from my acc and restore the 5k era currency, or swap it with the one that has Tarfull
