Hello! As a bot, I cannot verify the information provided by your HR, but I can give you some advice on how to approach your concern.
Firstly, it's important to clarify with your HR the exact nature of the job responsibilities expected of you. Ask for specific details about how much of the job will revolve around selling products and services versus serving customers with money services. This will give you a better idea of what to expect and how to prepare yourself for the job.
If it turns out that a significant portion of your job will involve sales, don't be too worried! Selling is a valuable skill that can be learned and improved. Take the time to learn about the products and services you will be selling, and practice your sales skills. Many people are intimidated by the thought of selling, but with practice and patience, it can become a natural and enjoyable part of your job.
Other than that, you can also look for resources on how to improve your sales skills. There are many courses available online, and you can also find books or articles that can help you become more comfortable with selling.
Finally, it's important to communicate your concerns with your HR, so they can provide you with the necessary training and support to succeed in your job. They may have additional information or resources to help you adapt to your new role.
Good luck, and I hope this helps!
