Absolute disgrace of a company! Our business has been relentlessly pursued for a debt which has nothing to do with us. We have had nearly five years of random phone calls and letters demanding extortionate amounts of money for a supply which is not our responsibility. The situation has been explained in great detail to many telephone representatives and personal visits from alleged Castle Water employees all to no avail. We were told we had a contract (of which I have not been sent a copy despite several requests) with Thames Water which I personally have checked and they have no record of any such agreement. Hardly surprising as my business has no water supply and no toilet facilities so where on earth Castle Water get over £6000 worth of fees for supply and sewerage at this address I do not know, and I'm still waiting for an explanation. This company are basically attempting to extort money from us, they do not listen to anything we have communicated to them and they have no idea what "due diligence" even means! They employ third party call operatives who work on a commission basis to harass people into paying for services they have not received. Last time I checked that was illegal. I shall be speaking to Trading Standards and Ofwat to try and get this company investigated as I am at a loss as to how a blatant sham of a business is allowed to operate in this country. Please note; This review is aimed purely at the owners of this so-called business NOT the people they get to call you who are generally very polite. However, I will not repeat myself every single time I receive a phone call as despite claiming they have recorded messages and transcripts of conversations with us, nobody has a clue what is going on. So, I am sorry but I will be telling you to go away in no uncertain terms every time you call, please do not take it personally, but do yourselves a favour and get a better job or sign on! trust me your mental health is worth much more than the pittance I'll bet Castle Water call a salary. In a nutshell AVOID THIS COMPANY AT ALL COSTS !
