Dear Sir,

I am writing to express my dissatisfaction with the new automated service recently introduced by your company. The service has proven to be quite challenging to use, and I have had to wait for an extended period to reach a real person when I encounter a problem. In my opinion, this represents very poor customer service, and I am frustrated with the situation.

I hope that you can make adjustments to the service as soon as possible to improve the experience for your customers. Thank you for your attention to this matter.

Sincerely, [your name]
