Dear [recipient's name]:

I hired your company to provide landscaping services at our home every Friday from May through September. However, on numerous Fridays, your landscaping staff has not arrived at our property to provide the services for which we hired you. Needless to say, we are frustrated by this situation and are seeking to resolve this quickly.

Please contact us as soon as possible at the phone number listed at the top of this letter. We look forward to hearing from you soon, and thank you in advance for your prompt attention to this important matter.

Sincerely,

[Signature]
