Bad frustrating service ever

I am frustrated and am puzzled to be thrown everywhere by everyone from online to store. I am trying to replace a card and link my credit to the new card. Replacement has been done. Linking is the biggest impossible right now. I've been told by 3agents to go to store to do the linking. I work Saturdays and went on Sunday and no one answered the phone when the Store manager tried to connect me. Advising that on Sundays the centre doesn't answer the calls. I asked for advice as I am unable to come on Saturday due to work, can I send someone to be at the store with all documents, Manager says yes. My daughter goes with all docs advised and the other Manager tells me , no, I need be the one coming to the store. My question is, how because I cannot take off time from work just to like a card, and online service told me to call, and when I did the call on my own I'm told to do to the store, and the store wants me there personally....REALLY, IS THERE REALLY NO OTHER WAY TO ACCOMODATE SUCH SITUATION, OR should I just cut off this card and close the account?
