We have to remember that companies are operated by people and sometimes the people don't have the company's best interest at heart. There are some cities for all companies where there is great service and also, there are cities where bad service is the norm. The difference is the managers and whether they care or not.
I suggest you find and uniform and linen managed services company such as, "Uniform Bright", who can help you with any needs you may have. There specialty is helping to prematurely and legally cancel a contract, negotiating a new one, taking you out to bid, historical bill analysis, managed services & an expert witness in the event of court or arbitration. They are not lawyers but they know how the industry works and can help you to navigate the pitfalls that are associated with deceptive practices and one-sided agreements.
If dealing with a uniform and linen rental company has been a headache for you and you no longer want to deal with them, you should talk with your lawyer or hire an expert.
