Balabala accusing customer of damaging product where in fact it was bought like that!!!

I am beyond disgusted and upset... First we purchase a nail dust collecting machine - we get home, plug it in and the fan doesn't even work. We then return the machine (fully aware of no refund), then decide to look for a playmate for my daughter to play on... One of those huge colorful foam like ones witj pictures etc on. We get home, excited tonmake use of it - and then.... Open it up - only to discover it has already been torn in one spot and due to we presume being old and rolled up for a while - it seems to have perished and is bubbling. We take it back, they refuse to exchange it! They accuse my 64 year old mother of breaking/damaging it herself 😡😠 My poor mom was left utterly irate and peed off, they were so rude!! You will not be seeing us again ever... POOR CUSTOMER SERVICE!!!
