Free Traffic Legal Advice

Hi all , wondering if you can help me here with best how to proceed, will try provide as much information as possible

 In 2023 - on 3 separate occasions , March , October and December , Horizon Parking Ltd based in Chelmsford , England, have issued me with 3 separate private parking fines

 They have now in the space of 4 weeks sent 2 chasers using the wording:

 21/06:'' you may not have responded to previous letters due to an oversight , if you dont respond you are making an active choice , we will take this as evidence of your intent not to pay''

 15/07/2024: ''previously, we treated your lack of response as an oversight  , now ,if you dont pay we will treat this as an active choice ''

 Previously i was told to ignore these as nothing can come of it as they are based in England and cant enforce anything because of this

 im just wanting to make sure this is the case , just for peace of mind or if someone can give me the best advice on how best to proceed

the original fine was for £150 but now has risen to £230 and now threatening legal action

 any help appreciated , thanks
