Basically I purchased an item on my card and paid it in full. A tiny bit of interest was added £1.15 and I’ve had a letter today saying I’ve missed the payment. Letter didn’t arrive until 4 weeks after said missed payment and it will show as a default. I’m in a right state as we are about to get a mortgage and I’ve ruined us for £1. Tesco are showing no care and I’m guessing it will go on my credit report. Is there anything I can say to them to avoid the default please help! I wish I knew before the 14 days as I wouldn’t have got the default
