It is currently impossible to identify an exact Tracked 48 item from the invoice. There is a "sender's reference" which isn't searchable on C&D nor does it relate to anything on a C&D item. I keep getting "oversize" charges on T48 items and have no idea why.

Secondly, T48 pricing should not be such a mystery. The prices for each band should be available via my account as well as the volume I need to reach to achieve better prices. Today, I phoned customer support to get my prices (I'm convinced I'm being charged more than I was quoted) and was told they couldn't tell me and I had to email special.pricing.team@royalmail.com.

I'm not convinced of the legality of not telling someone what they're paying for a product until the invoice arrives and, frankly, I'm getting tired of the games. We're talking about a manned mission to mars, it shouldn't be that difficult to know what my prices are before the invoice comes.
