I’m with you on this, knowing that when offering to repay the mum she’ll most likely say don’t worry about it my treat out of politeness, most people would insist but that pair of grimy money grabbers would probably say ok ta!The only explanation in my mind for the credit card failing is that Creepy deliberately gave Isabelle the wrong number. Lazy/Creepy probably ignored her calls because they knew she wasn't just calling to say hello so the friend's mum had to bail them out. It is obvious there are money problems and that tin can hasn't helped. They will probably try to sell it for double the price.
