[Equilibrium]

Cs from Amazon.es informed me that they were unable to verify the PR as no one answered the phone when they called. They suggested that I wait a month and contact them again in order to review their available options for the order. Are there any other ideas to resolve this refund? Should I contact the customer service representatives after a month, if the refund is denied after the month they told me to wait, should I contact the executive team directly?

I wouldn't be waiting. You're someone who's annoyed already and now they say wait a month. Act accordingly and keep the pressure on. Something along lines of you've done your part, why don't they do theirs and call again etc.
