To improve your customer support without it taking up a lot of your time you can use an FAQ or Frequently Asked Questions.
In the FAQ you add all the most common questions your company gets.
So when a person needs help they simply press the Support or Help button (you can name the button whatever you want). The system will then ask the user what their question is about and give them a set of different options.
Ex. 1. Open Hours
2. Adress
3. Return policy
4. Delivery policy
Based on the chosen option the system will give the user the answers.
Inside each category, you could even give the users more option
Ex. Delivery policy
1. Cost
2. Pickup options
or any other options that fall within that category.
