They are all charging on time basis. In some cases, they can charge you lump sum, but the service quality may be in doubt. They always persuade you to take retainer service, but the quality would drop after sometimes. When you want to privatize them, it would be extremely expensive and again, the quality of service will drop dramatically after the honey moon period. |
