We are trying to upgrade the license of our recently accepted Bioinformatics paper to Open Access license. However, the communication with the customer service of Oxford University Press is horrible. We are trying to arrange the license change since January 20, 2021. That is almost three months of useless communication. Every time we write a message, we wait several days to weeks for a reply. Moreover, different person answers every time. Do you have similar experience with OUP customer service?
