Have called 5 times in the last week. Refuse to take no for an answer. They have called within hours of the first call. They better hope they don't call again because whoever that poor telemarketer is on the other end is going to feel like the FBI is going to be at their door to arrest them once I am done with them. Trying to give you a $50 gift card for testing your water. Essentially they are trying to get a Tech (which is really a sales person) to tell you how bad the water is and to try and sell you a several thousand dollar water purification/softner system. Stay away from these people. There really name is Water Equipment Technologies.
