Hello everyone hope one of you smart people can help me out here. So I own a small business (A) , and the building that I operate from is owned by someone else who also have thier own business (W). The building used to be one building but it was later divided into two and had separate electric supply installed. We are next to each other. Now then, i have got 2 contract letters from 2 different companies, one about gas and one about electricity named to my company and the supply address for these letters is W's address. I only have electricity supply to my premises since I don't need gas and I have been with Eon. My account with them is clear as I always pay my bills. Now the thing I am getting monthly bills invoiced to my company and sent to my business address but the supply address on the bills show W's address. At the beginning i thought it was probably a mistake since we are next to each other and business neighbours. So I contacted these 2 separate companies telling them they are sending the bills to wrong address and they should send it to W's address and invoice it to them since they are using and paying for them. Each of them sent me a copy of contracts signed and on the contracts I see that the manager of W signed the contracts and showed himself as manager and put my companys name and number on the contract but gave thier bank details for direct debit. So even though they are getting the supply these accounts have linked to my company. After looking into this further I found out that W credit history has been awful and they already owe their previous supplier some money so i guess that's why they put my company's name on the contract as no one else would provide them a contract without security deposit. Now these 2 providers I have been in contact with still haven't removed my company's name from the accounts and to make matters worse today I received a letter from a firm about legal notice of proceedings saying they have been hired by Npower for t debt collection because around 10k is owed to them. Once again this letter et is sent and named to my company and the supply addresd is shown as W's. So clearly W has been using my company name and this is clearly a fraud. So I wanted to know what are my options and what can I do to get rid of this issue. I will be talking to W later this week but I don't think they will do anything about it. So who do I contact about this issue. Thanks in advance for any help.
