Tweet from Latam yesterday: Hello, according to our records the refund request was submitted the 26th of march(the regular process takes up to 20 business days). Additionally, due to the large number of reimbursement requests received, we have processed the refund process in the form of a travel voucher that is possible to redeem for LATAM services within the next 12 months(or request bank transfer) you'll receive an email confirmation regarding this process. Feel free to contact us back in case you've an additional query. Regards.

Since then, I cannot access the PNR through the website but still not received anything...
