Band 9: You have received a bill from a mobile phone (or cell phone) company for international call charges relating to a time when you did not use your phone for international calls. Write a letter to the company, complaining about this giving your reasons asking for the bill to be changed Begin your letter 'Dear --------' Do not write any addresses Write at least 150 words

I am writing to express my concern regarding an unexpected bill I recently received, which includes charges for international calls that I did not make. As a loyal customer of your company for the past five years, I have always appreciated your services and offers, which makes this incident particularly disappointing.

Upon reviewing my bill, I noticed additional charges for international calls; however, I have not used my phone for such purposes in the last two months. This has caused me significant confusion and frustration. I have heard similar complaints from other users, which raises concerns about your billing system’s accuracy.

I kindly request that you investigate this matter and adjust my bill accordingly. If this issue is not resolved, I may have no choice but to escalate my concerns to higher management, as it affects my trust in your customer service.

I sincerely hope for a prompt resolution to this issue, as I would like to remain a satisfied customer. Thank you for your attention to this matter.

Yours faithfully,
