I have visited the RGA Concrete LLC located at Building 104, Porter St Street, San Antonio City. The company seems to have a decent reputation with a rating of 4.5 from third-party ratings. However, upon closer inspection, I noticed that the company has a limited operating schedule, open only from Monday to Friday, 8am to 6pm. This might be a limitation for customers who need concrete services outside of these hours.The company's website is active, and it provides information about their services, including concrete contractors. However, I couldn't find any information about their payment terms or policies, which raised some concerns.One of the customer reviews highlighted a serious issue with the company's payment practices, stating that they were not paid for two weeks of work and were still waiting for their payment. This review also mentioned that no one answers their phone calls, which is unacceptable.On the other hand, I found a few positive reviews praising the company as "good" and "the best in Texas." However, these reviews were not specific about the company's services or qualities.Overall, I would caution potential customers to exercise extreme care when dealing with this company, especially regarding payment and communication.
