Other Mail Services?? POP??
I may be worth a trip to POP to pick up your mail, perhaps every 7, 14, 21 days? There are 2 honest & competent mail services in POP: Business Mail, Plaza Turisol, & Xmail, 12 de Julio, near the RUSA Cambio. Both might be worth investigating. Inconvenient? Perhaps. The lesser of 4 evils? Time will tell. Good luck.
