Been 4 months for Cox installation

I paid over $5,000 to Cox to have high speed run 3 houses down from my house (since we didn't have it before). The Cox construction planner and his team were quick to collect my money, but do not answer my emails, texts, or calls anymore. I do not know where to turn as my local cox store doesn't have the information and the construction team doesn't have a public phone number to call into.

This is in Macon, GA. I need help as this wait is really ridiculous, as I work from home and need this.
