If necessary, you can also contact the relevant CPSP directly with your question: In this case your bank statement shows the CPSP as the beneficiary of the payment. This is the Institution that processes the payment on behalf of the company. Sometimes a payment is processed by a CPSP. The money will be forwarded by the CPSP to the company webshop where you have ordered. For you as a consumer this makes no difference. The name of this CPSP is shown on your bank statement.
These parties are called Collecting Payment Service Providers (CPSP). Many companies/webshops leave the collection of the money to third parties. In many cases this is not the company where you ordered the product or service. The description of the iDEAL-payment on the bank statement always contains the name of the company that receives/collects the money.
