j'ai commandé cette pompe le 30 juin. Le 1er juillet je reçois un mail du transporteur avec le numéro de colis. Mais le transporteur n'a pas reçu ce colis. Injoignable par téléphone. Mail adressé à Prato Erboso le 08 juillet...suis en attente d'une réponse... qqu'un a t il connu le même sort ? Si oui, est-ce résolu positivement ? Comment avez-vous procédé ? Merci à vous
Réception rapide du produit conforme à mes attentes. Installée très rapidement en remplacement du même modèle qui a duré 11 ans sans soucis particulier. Pompe monobloc indémontable donc remplacée. Merci !
