Driving Licence and CPC Card

Im based in northern Ireland, passed my C in November past got licence back after 2 weeks, came back with on C marked on it but no C1 after 3 weeks of trying to ring them with no joy emailed them as to why c1 wasnt marked up on photocard they said no we only mark photocard with category that you took a practical test for, but can still drive c1. Then did cpc mod 4 test at start of january still havnt received my card( 6 weeks and counting) emailed them last week asking what the craic was told that there computer system wont upload that i passed cat C onto their system therefore wont issue me my card but said i can continue to use my certificate as proof of cpc.THEN i asked the question is this going to affect me doing my c+e as ive it booked for end of march still awaiting a reply on that 1
