If you only get a few messages you may be able to be a class representative in a class action and get more money than you could as an individual plaintiff.
On the other hand if you have many calls or texts you may be able to get thousands of dollars more in damages. For example if you got 30 calls or texts you could be get as much as $15,000 to $45,000 in damages. Most class action representatives get a few thousands dollars. That’s why it may be better to stay with an individual action.
