What is bol.com's right to dupe a seller?

Questioner

I have been a seller at bol.com since this year. Now there is a customer who wanted to mislead me. I delivered an antique cupboard and the customer claims that he had to pay 25 euros in delivery costs, which is not the case! There is also no receipt for this. Furthermore, the customer claims that there is woodworm in the cupboard. This is also not true; I am not going to sell a cupboard with woodworm?! When I delivered the cupboard, the customer told me that she had a plan with it. Apparently this was her plan, to try to dupe me. Bol.com apparently always protects the customer against the seller. I receive all kinds of threats from bol.com, while this person should be a ''mediator''. What can I do about this? Can I object to what bol.com says and that it will become a lawsuit? I would like to hear it. Thanks in advance. See here what bol.com writes: Unfortunately I have not received a response to the e-mail below. I would like to receive this within two working days at the latest. If this does not happen, we will be forced to resolve the matter in the customer's favor and reclaim the payment from you. This will also be reported to our performance team regarding the deduction of policy points. Policy points I would like to draw your attention to a bol.com service standard in your account, namely policy points [https://partnerplatform.bol.com/nieuws/nieuw-in-het-verkoopaccount-beleidspunten]. You start with 100 points and in the event of a violation, points can be deducted from them. After a year, these are also credited again, so that you end up at 100 again. As long as you do not reach 0 within a year, there are no further consequences. However, if you do reach 0, your sales account will be closed. Any other sales accounts you may have will also be closed immediately. Why are the policy points relevant here? When you started selling on bol.com, you agreed that you would sell in accordance with our General Terms and Conditions and the law and regulations. We have come to the conclusion that you are not adhering to this. We request you to improve this and if proper cooperation is not provided, this may lead to a deduction of policy points. Can this still be prevented? Yes. You can consider this email as a warning. If you do not resolve this with the customer within 2 working days, we will be forced to inform Partner Performance Management and policy points will be deducted.

Lawyer

Does the customer claim that there is woodworm in the cupboard or does the customer prove that already? Otherwise I would say that bol is taking the law into its own hands now that the various claims have not yet been established in all reasonableness. I advise you to read the entire set of conditions carefully or have them read to see if there is an escape built in that works to your advantage.
