Freepost usually takes the same length of time as the matching service so 2-5 days on average.
A "returned back to sender" has no particular delivery timing as its a free service and the paid for the part has already been serviced. Live mail takes precedence in the system and "RTS" is classed as "dead mail".
Its also unusual that a Freepost Address is the return address for refused mail, not unheard of but unusual.
Another point is that Royal Mail won't be able to redeliver a returned/refused if its normal mail as there is no way to track it and with 40,000,000 items daily trying to find 1 letter really is a small needle in a massive haystack.
I am afraid all you can do is wait for the company to process their returned mail and if they get a lot (like mailing houses do) it may be a lengthy wait.
