Horrible customer service. I've been a customer for over 15 years, and they keep sending me emails about making referrals. I finally make 1 referral, and they credit my account with the bonus, then take it away with no explanation. When I ask why, they lock up my account and accuse me of trying to cheat them with the 1 referral! The person I referred does not have an account with them, but Rakuten insists he does. I can't believe how badly they're treating me after 15 years as their customer. I will be taking my business to Topcashback from now on. They have higher rebates, and decent customer service, unlike Rakuten.
