BAD EVERYTHING AT GAME

My fiance has an account with Game but we have been struggling with the account since day 1. We always pay on time and more than we should. Everytime we purchase something on the account the card gets blocked. We have been unblocking the card evertime OVER THE PHONE for about 3 times this year alone. Today (31St October 2020) we tried to purchase something at Makro store and we were told the card is blocked AGAIN! We phoned to get the card unblocked AGAIN like we usally do but we were told the card is damaged. The previous time we were told the card was outdated. We got the new card 2 months ago and only used it ONCE! The consultants keeps telling us to go to a Game Store to get the card unblocked but why the first 2 times they could unblock it over the phone? And why does the card keep blocking? I am not going to drive to Game Store AGAIN as I don't have the petrol or time everytime his card gets blocked.
