Battlefield 1 Revolution missing DLCs

So am I given to understand that if you have purchased Revolution to follow on from your original purchase of the game it is only fdor those wishing to use multiplayer mode? I was't informed of this when I purchased Revolution from EB Games, and on subsequent occasions when I queried why I could not see the add-ons in the Map Screen (nor play any of the add-ons) neither yourselves (EA Games) or the provider (EB Games) mentioned this to me despite my assurances I was not into online playing or multiplayer gaming. If this is indeed the case then I have been ripped of my purchase price and am not happy this has not been sufficiently explained or understood.

My issue has been that since purchasing Revolutions and witnessing it to be installed on my PS4 I have not been able to play any of the new levels or even see them having been added to the game via Map levels. I have taken my query to EB Games and yourselves at EA Games and on each occasion nobody has asked me if I am using single player or multi player. I have (as above) expressed my particular gaming needs and nobody has questioned me or referred to 'Multi-player only' levels. Both EA and EB suggested it may be a licences issue on my PS4 or even my own, personal account settings. I have checked my system several times, even deleted and reinstalled Revolutions only to find nothing different - no additional levels but confirmation of being installed somewhere in my PS4. To be honest I am deeply disappointed.

IF the new levels CAN be played in SPM and I have misunderstood the above (previous) comments and responses to users then can anyone please help a frustrated old fool as I have 'as yet' struggled to find a way around my own problem in playing the new levels.
