When two service instructions point to different next steps, the customer should treat the conflict as unresolved rather than assume that either instruction automatically overrides the other. They should compare the exact wording, check the accepted contract terms, and set out the discrepancy to the business in writing.
How to check the conflicting instructions
Compare the wording
UK consumer-contract guidance warns that wording should not be vague or open to many interpretations. If two instructions lead to different actions, the customer should identify the precise phrases that create the ambiguity and keep a copy of both instructions.
The useful question is not which message appears more recent, but exactly what each instruction requires. The cited guidance does not establish a general rule for deciding which of two instructions controls.
Check the contract terms
Australian consumer guidance recommends reading and understanding the terms and conditions of a service contract before accepting it. The customer should therefore check whether either conflicting instruction appears in those terms and compare it with the wording that was accepted.
A separate instruction may be unclear, but the customer should not assume that this alone determines its status relative to the contract.
Put the problem in writing
Consumer guidance from the Australian Competition and Consumer Commission notes that setting out a complaint in writing can give the business a clear account of the problem and preserve a record.
A written complaint should identify both instructions, explain how their next steps differ, and ask the business to clarify which instruction it considers applicable. The customer should retain the relevant messages, contract terms, complaint, and response.
What still needs confirmation
The available guidance does not decide every conflict. The customer must still confirm:
- whether either instruction forms part of the accepted terms and conditions;
- whether the business will treat one instruction as applicable;
- how the business explains the difference between the instructions; and
- whether jurisdiction-specific rules or another applicable source affects the answer.
The guidance supports clear wording, understanding the contract, and keeping a written record. It does not promise that a complaint will produce a particular clarification or that either conflicting instruction will automatically prevail.
