Excellent Service – My Fifth Boost and Still Fully Satisfied

German:

Ich habe einen Boost für einen vollständig AFK durchgeführten Mythic+16-Run gekauft und bin erneut vollkommen zufrieden.

Obwohl ich den Boost aufgrund eines medizinischen Notfalls für eine Woche unterbrechen musste, war die Kommunikation jederzeit unkompliziert und verständnisvoll. Nach meiner Rückkehr wurde alles problemlos fortgesetzt und wie vereinbart abgeschlossen.

Inzwischen war dies bereits mein fünfter Boost. Ich habe bisher alles genutzt, von kleineren Mythic+-Boosts bis hin zu Cutting Edge inklusive Mount. Die Abwicklung war jedes Mal zuverlässig und professionell.

Klare Empfehlung!

English:

I purchased a fully AFK Mythic +16 boost and, once again, I am completely satisfied with the service.

Due to a medical emergency, I had to pause the boost for one week. The communication was understanding and straightforward throughout the entire process. Once I returned, everything continued without any issues and was completed exactly as agreed.

This was already my fifth boost. So far, I have purchased everything from smaller Mythic+ boosts to Cutting Edge including the mount. The service has always been reliable and professional.

Highly recommended!
