Problems, Refunds, and Disputes
Most issues are resolved fastest when the customer and vendor clearly document what was agreed, what occurred, and what remedy is requested.

Quick note: A factual timeline is more useful than a conclusion without evidence.
Contact the vendor first
Use the order messages to describe the problem, attach relevant evidence, and propose a reasonable next step.
Preserve the record
Keep quotes, messages, appointment details, photos, delivery notes, and receipts connected to the order. Do not alter equipment evidence when safety permits it to remain undisturbed.
Request platform assistance
If direct resolution fails, use the order record in your account and the available dispute or support process. RTN may review platform records and facilitate communication but does not guarantee a particular outcome.
Safety comes first
Stop using equipment that may present electrical, fire, laser, mechanical, chemical, or other hazards and seek qualified help.
