You're override $objectManager variable value in :
$store = $objectManager = $objectManager->create('Magento\Store\Model\ScopeInterface');
change it by :
$store = $objectManager->create('Magento\Store\Model\ScopeInterface');
Change your email variable with :
$email = $this->scopeConfig->getValue('trans_email/ident_support/email',\Magento\Store\Model\ScopeInterface:COPE_STORE);
COPE_STORE);
