Luno Poor customer service

I created an account on Leno and did all thr necessary verifications. I credited my wallet, and since then I've been unable to do anything except deposits... I can't buy and sell crypto and I can't withdraw either. I keep getting an error message From the app saying "sorry for the interruption we couldn't complete that action". I've tried to contact the customer service to no avail because there isn't any response. Only an AI generating a reference code and getting a mail saying the message has been sent but there isn't any feedback. I really do need that money back. I'm from Nigeria by the way

My email address is: *** Phone contact: +***552
