Tls Contact's Unresponsive Service Creates Hassle for My Family Visa

I applied for visas through Tls Contact so that my wife and our baby could go to Switzerland, but I'm currently dealing with a frustrating situation. When I call them, they don't answer, and they don't answer any of my emails. We don't have much time left, so I need answers as soon as possible. Even though I've been trying hard for the past three weeks, I haven't heard anything. Is the amount of work they have to do really that much? Because the questions I have are important, I need answers quickly. I'd like to talk to someone from the right department. I'd be grateful if you could get in touch with me as soon as possible or answer the questions I have. Thank you.
