Rcs

I have app**** for insurance due the lockdown.I have a letter that clearly states that I am on unpaid leave because of no work no pay and I will not be working until the lockdown has been lifted.insurance has only paid for 1 month and rcs asking me to send them proof of no income again.I had already done that but they sending me emails stating my account is in arears and that I need to make payment. This is unfair as this is going to affect my credit record . Its also unfair as I am paying for insurance but it only pays for one month yet I have given a letter stating im not working until the lockdown has been lifted on no work no pay
