The problem was that we got a custom attribute called parent who was being called by search criteria each time magento tries to retrieve the customer parent it load it again and again do we end up that infinite loop, to fix that problem I use now customer collection and this is code snippet :

old code :

$searchCriteria = $this->searchCriteriaBuilder
            ->addFilter(CustomerInterface::WEBSITE_ID, $customerWebsite)
            ->addFilter(CustomerInterface::HIERARCHY_LEVEL, $parentLevels, 'in')
            ->create();

        return $this->customerRepository->getList($searchCriteria);

new code :

return $customer->getCollection()
        ->addFieldToFilter(CustomerInterface::WEBSITE_ID, ['eq' => $customerWebsite])
        ->addFieldToFilter(CustomerInterface::HIERARCHY_LEVEL, ['in' => $parentLevels]);
