Updating existing Excel datebase - Netherlands

I would like to receive a price quote for checking customers according to the following details: Territory: Netherlands
Number of records: 58
The purpose of the conversation: to find out if the company still exists and why they stopped buying
Background: We are a company that sells aluminum frames for the sign industry to sign manufacturers in the world, including Netherlands. These records are of companies that have purchased from us in the past for some amount. From 20 euros to hundreds of thousands of euros, and they stopped a year or more ago.
The purpose of the conversation is to check whether the company still exists, whether it is still in the field and why they stopped purchasing. We have prepared a dedicated link for filling in the results of the conversation. https://form.jotform.com/240311980841452 I am attaching the excel file with the records, the script of the conversation. (I translated it into Dutch on Google, it must apparently be proofread) The conversation must not be mechanical, the script is only for illustration. I have prepared several questions and answers in case it comes up in the conversation. For the purpose of the conversation, you work at Vista System Netherlands. Some of the records include several people in the same company, it is enough for us if you talk to only one of them.

I am attaching several files with instructions and questions for the project, it is important to go through them before starting the project!

Thank You.
