Sorry stupid fat fingers hit post too soon 

*have been struggling with various debts and today I have come home to this letter from Phoenix Commercial Collections LTD:
"REMOVAL NOTICE
I have attended your property to collect the sum outstanding of £amount (inclusive of fees and costs, on behalf of the above named client) or remove your goods for sale at public auction.
If I fail to receive contact to make arrangements for the collection of the above balance, I will return at a time convenient to me.
You do not need to be at the property for me to remove your good"
There is a mobile phone contact number handwritten at the bottom with the name Brian however there is no signature or anything else.
I'm confused for a couple of reasons:
A) the envelope was addressed to me and DP, however the letter itself only has DPs name on
B) the letter states that the date of visit was yesterday (3/5). I was home all day yesterday and did not have a single knock on the door or have the bell go (live in a very small 1 bedroom flat so no chance I wouldn't have heard it)
I have spoken to National Debtline's online web chat service and they have advised me to speak to CAB in the morning (which I plan on doing). I also tried ringing the number provided, but no answer so left a message.
Can anyone give any advice regarding this other than talking to CAB? Would be very much appreciated.
