On the other hand, i didnt experience any errors or problems with Changely when making some instant swaps to other coins thats
why i cant tell specific time frame on how long they would resolve it out but i can assure that they would able to resolve that out.
User experience certainly plays a part in how you trust a service. I've seen several problems with Changelly from many users in this forum. So Changelly is questionable at one point or another.
Even the reputable or best ones do experience such issue thats why it isnt really that surprising that any running services now do have corresponding problems have been faced
by into its users.
@OP, you should give some updates if this issue had been resolve or still pending as of this moment.
