Statement to Our Competitors
Cortez Services is committed to providing the highest quality of service while maintaining economical pricing. During the past five years, prices for toilet service in the San Antonio area have remained the same and, in many cases, have been lowered by businesses that are willing to sacrifice quality of goods and services in order to gain customers. Providing the lowest pricing does not equal providing the highest level of service. Cortez Services is not interested in lowering prices to a level that will deteriorate the price market in San Antonio, while simultaneously eroding service levels for the customer. Our goal is to have complete customer satisfaction. In order to achieve that goal, we must give our customers the highest value for their money, which cannot be achieved by being low price-oriented. Cortez Services continually updates equipment to increase quality of service and continues to maintain the highest level of customer satisfaction in the industry. Most important, we provide the customer with the services they deserve and give them the best value for their money at reasonable prices.

Our customers appreciate getting hassle-free, accurate and complete service from Cortez Services, an ethically committed business. This is why we make an effort to caution our customers to be aware of “low cost/low service” companies that do not share our dedication to superb quality or outstanding customer service.

At Cortez Services, we pride ourselves on maintaining comparable prices to our competitors, while still leading the industry in customer service. Cortez Services strives to remain in that position for the future.
