I have purchased from the dealer two products. Once the water softener for the washing machine and detergent for the dishwasher. The seller therefore cashed twice this Porto totaling each 4.99 EUR 9.98 EUR total, although both bottles were delivered in a package. It was a small package for 4.99 EUR DPD Porto. A refund of the overpaid Porto rejected the seller on the grounds that are to be paid of 4.99 EUR for each purchased product Porto. With what justification please? For me, the customer rip-off. The Customer knows neither good day even Sincerely and also answered yet cheeky back. Thank you for this experience.
