Hello, Looking for some advice on an issue I currently have with Three UK. In 2013 I rang Three to discuss a cheaper tariff for my ongoing phone contract. The call went well and they offered a new tariff at £15 a month. Brilliant! However, last week I received a demand for payment for a three account that I had no idea was in existence. It appears the new £15 a month tariff was actually a new contract! I was under no impression that when I agreed to £15 a month they were in fact opening a new contract in my name, and not changing the tariff on the contract I already had in place with them. Three are not being helpful at all - they say that when I used the new £15 a month deal I accepted its terms and conditions. They did send a new sim but in my naivety I just thought this was normal practice for changing tariffs. I should have checked this, but at the same time I had no further contact regarding the original contract, which was accruing monthly line rental up until the point they cancelled the contract due to non payment - some 2 years ago now. No request for payment has been received until Lowell sent me a letter saying they have bought the debt (including a dodgy looking notice of assignment from Three). All correspondence with Three has been with their Executive Office, and they are flat refusing my version of events and claim I must have known there was two contracts as I have used the sim card in question. They can't provide written or verbal evidence that I accepted the contract while on the phone back in 2013. The new/later contract was issued by their direct sales team in Glasgow over the phone. Could anyone suggest the best line of action from here? Thanks for taking the time to read.
