We used this water company for donating water to local religious charity when Bronte water was taken over by this Culligan water/ Water Logic. We never had problem with the former for years. But there was problem with Culligan and we stopped using them. At one point, they failed to collect empty bottles. When phoned they collected but still charged us £50 for empty bottles that has already been collected from the address. Despite repeated attempts by phone and in writing including speaking to the customer service they did not amend the invoice but harassing us with incorrect overcharged invoice. Their customer serviced does not work. When wrote to them to the email address provided in the bill, they never responded except the automated replies. I spoke to customer service, and asked them to acknowledge the compliant but it was a waste of time, as I never heard anything back from them regarding my concern and problem. Instead, we received the same invoice days later. They showed no respect to the customer. Very disrespectful, ineffective and negligent customer service who cheated the customer in my experience. I have paid this incorrect bill as it stands losing £50 as I want to put a stop to the pending invoice but I was cheated, neglected and robbed by the Culligan. The delivery van also turned up at the billing address for water delivery not at the correct delivery address at one point. So inefficient and disrespectful. Very unpleasant experience as you can imagine me having to write this review. Please stay away from them unless you want the water delivery turning up at the wrong address and being robbed.
