I recently bought 7 packages from different sellers. Only two of them actually sent me links to SERP tracking for my package and none have sent me the reports. It is still early (it's been 8 days) but as time is valuable and I want to test out many different services I didn't do too much research as to if their reviews looked fake, etc. What is standard for delivering reports/tracking? I emailed some of them about it and never heard back but I don't want to call anyone out. Also if I do get ripped off is there a time limit I need to do it by to do a paypal chargeback?
