Thankfully most carpet cleaning companies are legitimate, trained professionals who will offer a high quality service at a fair price and strive to meet the needs of their customers every step of the way. However, as in all public services there will always be unscrupulous operators who will take advantage of the unwary by offering a deal that’s ”too good to be true” only to arrive and increase the cost with hidden additional charges such as ”the cost quoted was for a basic clean and you need a deeper clean”, ”you need extra chemicals that will increase the cost”, ”those stains will incur an additional charge”, This technique or scam is known as ”bait and switch”.
