Dear [Recipient's Name], I hope this letter finds you well. I am writing to express my strong disagreement with the recent bill I have received from [Company/Service Provider]. Having thoroughly reviewed the bill, I believe there has been an error in the calculation, resulting in an inflated amount due. First and foremost, I would like to emphasize that I have been a loyal customer of [Company/Service Provider] for many years and have always paid all my bills promptly and in full. Therefore, it is quite disheartening to encounter such an erroneous bill, especially considering the trust I have placed in your organization. Upon analyzing the detailed billing statement provided, I noticed several discrepancies that I would like to bring to your attention: 1. Incorrect Meter Reading: It appears that the meter reading recorded for the current billing cycle is substantially higher than the average usage, which seems highly unlikely. I kindly request that you double-check the meter reading and ensure its accuracy. 2. Incorrect Rate Application: While going through the billing breakdown, I noticed that the rates applied for certain services mentioned in the bill do not correspond to the agreed-upon terms outlined in our contract. I kindly request clarification on why the rates have been deviated from our agreement. 3. Missing Discounts/Applicable Credits: Additionally, it seems that the bill does not reflect the discounts or credits that I am entitled to as per our previous communication or any ongoing promotions. Please review my account details and revise the bill to include all relevant discounts as soon as possible. Given the aforementioned concerns, I kindly request an immediate investigation into these billing discrepancies. I assure you that I will not be able to make the payment until these issues are resolved. My current financial situation only allows me to pay the correct amount, not the inflated sum indicated on the bill. I would appreciate prompt action in rectifying this matter, preferably within [number of days] from the receipt of this letter. I sincerely hope to maintain our positive business relationship, and I trust that this issue can be resolved amicably. Please provide a written response within the specified timeframe, addressing the concerns raised. You can reach me at [Your Contact Information] to discuss a satisfactory resolution to this matter. Thank you for your attention to this dispute, and I look forward to receiving your prompt response. Yours sincerely, [Your Name]
