Account

I am writing this with a very broken heart of what Jet store did, after so many years of having an account with them, I have lost my job years back due to covid, so with the little money I got I decided to pay off my account, I was only left policies, last year I started receiving calls from them saying I owe them 6000,i have asked them several times to send me statements or even signature of the person who was signing up for those, still nothing because I have never taken clothes from them...
