Property damage

We have $8900 worth of property damage from AT&T (that continues to increase each time it rains). I have been trying to get this resolved since Jan of 2022. I was told yesterday that if AT&T contracted a third party to trench our yard that our case would be dismissed with them and we would need to take it up with the third party. This is absurd as our contract is with AT&T and the crew who came out to do the line never alerted me of their arrival and started to destroy our yard immediately. I had a delivery driver alert me of the disaster they had caused. It has been horrible as I have a toddler and another baby on the way so I do not have the time or energy to keep fighting this. The damage is also quite extensive and not something we can just pay on our own. I saw a post about contacting the BBB-is that the best way to get this resolved? Hiring an attorney would also cost money and would defeat the purpose. The sad part is I've used AT&T for years and this has shown so much about the company and their lack of ability to do what is right. I honestly do not know how they are still in business as so many others have been shown such disrespect as well.
