Strange uncalled for complications

Received E Mail from Clicks that I have 2 Clicks cards conflicting with points allocation system. Called in to 0860CLICKS as instructed on 13th June 10h40. After 3rd attempt (cut off on first 2 attempts after waiting for 10 minutes per call) was informed I would need to link card - WICH IS ALREADY LINKED with Discovery. This was done, completed and confirmed earlier in the year on receiving new Clicks/Discovery Vitality card. Really disappointingly bad service from the company. Instructed Clicks to cancel card.
