        \Magento\Customer\Model\CustomerFactory $customerFactory,
        ...
    )

        ...
        $this->_customerFactory = $customerFactory;
        ...
    }

    public function getFilteredCustomerCollection() {
        return $this->_customerFactory->create()->getCollection()
                ->addAttributeToSelect("*")
                -load();
    }

        ...
    )

        $this->_customer = $customers;
        ...
    }

    public function getCustomerCollection() {
