i had a visit from these this morning, im in arrears with my council tax and these are dealing with it, they wanted £93 pw , i i paid £200 the first week £95 the second then told them i could not afford the 93 pw, i had a visit today and i said i could pay £50 pw , the agent said yes thats fine but i would not let him in so he said the agreement is off i will expect payment in full by the end of the day, he said do not contact my office as they will only refer you back to me, im worried sick , i wont to pay it off but cannot afford the full amount in 1 payment, my property is rented and furnished by my landlord but dont want him involved, any advice will help ty
