SPOT ON belowIt is against the law to have your post sent to another person / business address!! if you have no contract with them or they are registered business centre / address - WITHOUT PERMISSION
So it's that confidential that CLEAN does not have a sign at the entrance of CJ Transport stating that "this is the registered trading address of CLEAN" don't you have to do that? And why would the people there not know anything about CLEAN, and could not figure out why post was arriving for CLEAN, I think that MD needs to let his employees know! It's a good job you did not turn up for a cup of tea and cake Simon, Nobody from CLEAN would of been there.
How dose the postman find the address if no sign!! it must be addressed to CJ Transport,or Clean C/O CJ Transport
