A call girl or female escort is a sex worker who (unlike a street walker) does not display her profession to the general public; nor does she usually work in an institution like a brothel, although she may be employed by an escort agency.

The client must make an appointment, usually by calling a telephone number.

Chandigarh is a city and a union territory in India that serves as the capital of the two neighbouring states of Haryana and Punjab.

The city is unique as it is not a part of either of the two states but is governed directly by the Union Government, which administers all such territories in the country.

Cash on delivery (COD), sometimes called collect on delivery, is the sale of goods by mail order where payment is made on delivery rather than in advance.

If the goods are not paid for, they are returned to the retailer.

Originally, the term applied only to payment by cash but as other forms of payment have become more common, the word "cash" has sometimes been replaced with the word "collect" to include transactions by checks, credit cards or debit cards.

An Escort agency is a company that provides escorts for clients, usually for sexual services.

The agency typically arranges a meeting between one of its escorts and the client at the customer's house or hotel room (outcall), or at the escort's residence (incall).

Some agencies also provide escorts for longer durations, who may stay with the client or travel along on a holiday or business trip.

While the escort agency is paid a fee for this booking and dispatch service, the customer must negotiate any additional fees or arrangements directly with the escort for any other services that are not provided by the agency involved, such as providing sexual services (regardless of the legality of these services).
