Very bad Tyres and no replacement

Separation on all 4 tyres, 205/65/16 Firestone touring. NO REPLACEMENT tyres, I was told to drive like that. NOW I put on continental. NO MORE FIRESTONE OR BRIDG for me, thank you. Neo from Bridgestone said he will refund the price of the Firestone, however the continental are much more expensive than the Firestone, I will have to pay for the alignment and the extra from my pocket
