Statement: "I have not received telephone bills for nine months inspite of several complaints" - A telephone customer's letter to the editor of a daily Assumptions: Every customer has a right to get bills regularly from the telephone company. The customer's complaints point to defect in the services which are expected to be corrected.

Given data

• Letter: No telephone bills for nine months despite several complaints.
• Assumption I: Every customer has a right to receive bills regularly.
• Assumption II: Complaints indicate service defects expected to be corrected.

Concept/Approach

The grievance presumes an entitlement and that complaints should trigger corrective action.

Step-by-step reasoning
Claiming non-receipt as a problem presumes a right/expectation of regular bills ⇒ I.Making complaints and writing to the editor presumes there is a correctable service defect ⇒ II.

Verification/Alternative

Without (I), there is no legitimate grievance; without (II), complaining would be pointless.

Common pitfalls

• Viewing the letter as mere information rather than a corrective appeal based on entitlement.

Final Answer
Both I and II are implicit.
