Please Return My Call Letter

Hello Sandy,

Text me a landline where I can call? I have to talk to you about your progress report so that we can approve the contract by this week.

Best regards,
Didier

Please Return Call Letter

Dear Mr. Marin,

Let me know what's the best time to call you on your mobile phone. Unfortunately, I have no landline at the moment. Please get back to me as soon as possible. I have very good news.

Thanks,
Leo
