I wanted a refund for an ‘exploding’ table, but Argos shattered the idea

Our Sicily table disintegrated and I understood it was a common faultI bought a glass-topped garden patio table from Argos in Banbury in April, but in July the top suddenly “exploded” on a sunny day, shattering into pieces for no apparent reason. This was potentially dangerous – luckily no one was hurt – and, of course, the table is unusable. So far Argos “customer care” is insisting this is “accidental damage” rather than a manufacturing fault. Ho
