I purchased 4000 followers and they were delivered within a week. After a month I lost all 4000 so I complained. It took several emails to get a response from bulkoid but they did a refill and I regained those 4000 followers. Shortly afterward I lost them again, I emailed a few times but was ignored. This service is real and delivers but it's only temporary and the customer service is awful.
Do not buy from them! You will lose your followers as quickly as you gain them!
