Are Sandisk SD cards from Argos always genuine?

If you buy from Amazon or Argos but NOT marketplace sellers on there, you should be fine.
Test cards are the stated capacity with https://h2testw.org/
Lastly, there could be other reasons your cards are corrupting:
- interrupting the power during write operations
- using a normal micro SD card in a dashcam, doorbell cam, raspberry pi. These make frequent writes to the card which wears out the memory cells. For purposes with constant writing of data, buy high endurance SD cards.
- using too small a card for the frequency of write operations. Again, the memory cells wear sooner than in a higher capacity card where the writes can be more distributed.
- when the price is too good to be true.
If you provide more detail about the card brand, capacity, and what you're using it in, people can give you a better idea of where the problem originates.
