At the beginning, I experienced significant delays and communication issues regarding my order, which honestly caused serious concern because the parts were urgently needed for an important project.
However, after continuous follow-up, the Propel Parts team handled the matter professionally, provided shipment tracking, and the parts finally arrived successfully.
I especially appreciate their willingness to communicate, acknowledge the issue, and continue working toward resolving the situation.
In international business, delays can sometimes happen, but what matters is the final commitment to resolving the issue properly.
Thank you to Daniel and the team, and hopefully future transactions will be smoother for both sides. -
