Order number AN19B03T3520-21SWW2 My drone battery was sent after 9 days and it was faulty / defective / dead. As requested, I sent a detailed description and a video to the company. Kelly, in the warehouse customer service said I must pay the return shipping cost (€25) or they would offer me €4 for me to get it repaired. This was then increased to €7 and the to 50% which is €20.12. After 3 days of arguments, several e-mails, and only after I posted negative reviews and threatened a Paypal claim, the company agreed to a full refund, but would not reinstate the points I used to part pay for the order, so I did not get the "full refund" promised. . If you want to risk a purchase from this dispicable company, then you should use Paypal, which gives protection. If you encounter a problem, then contact Tomtop customer service. If they mess you around, then post negative reviews everywhere and threaten to file a Paypal dispute. This will get their attention. If you do not get satisfaction, register the problem with Paypal, who will review the case and has the power to refund you. If you register the problem with Paypal, DO NOT CLOSE the file unless the case is resolved to your satisfaction, as once closed, the file cannot be reopened. I have had other successful purchases from Tomtop, but when things go wrong, their back up service is terrible. They will try everything to avoid responsibility and will try to intimidate. Stand your ground and you will eventually get what you are entitled to.
