RMG has had a spell of silly administrative errors of late. The letter about sublets was supposed to only go to those who have a contact address other than Rainbow Quay. The storage of items in the electrical cupboards is a health and safety issue and was raised by the fire officer who visited Rainbow Quay. The final demand you have received could be for your water bill? It is billed at part of the service charge. Thus if your late paying your water bill, even if you pay your service charge by standing order your could still get a demand. The exception to this is if your monthly payment exceeds your service charge in which case it shouldn't happen. Drop them an email and ask them to explain what its for. If it is another administrative error let me know.
