I believe each company should have a phone number available daily for their customers, even if the company or the business is small/big. In this way, you give the clients more trust in our products and services, and even if you can't afford to hire a full-time phone assistant, you can always use the TMC'support services. I use their services, and I couldn't be more grateful since they are at a very affordable price and they organize my clients in the best way possible, so I have time for everybody and save me a lot of time.
