Hi Mat_Davies,
I'm sorry to hear you've been having some problems with the return of your equipment. Due to postal delays caused by industrial action, there is a slight delay on receiving some pre-paid packaging - however, this should not be a prolonged period of time.
In regard to the Manned Collectors, these are also based on the availability in the area, and can be impacted by various factors such as sickness and Technician availability. I'm going to drop you a private message to discuss the available options for getting this resolved. Please look out for it in the top-right, purple envelope.
Thanks,
