Nobody is going to offer you a way to trade your pinks, at least here in the UK.
And where and how did you buy them? Was it from a cold call, if so, sorry to be the bearer of bad news but they're probably worthless and the money you paid to the brokers was stolen from you.
Write the loss off to experience and in future never buy a financial product that you haven't fully researched plus of course fully check out the broker you're dealing with.
Good luck anyway.
