Mapsensor delivery

So I am faced with a map sensor issue on my vehicle and decide to use OnlineCarParts since they provide door to door delivery. The call was made and the part was ordered, the address and mobile number was recorded during the ordering process. So today I waited until 11h30 and decided to call hoping I would get an update on when to expect the delivery. The sales consultant was not sure on where the delivery vehicle was and stated that the driver would call before lunch. Three hours later I call again to be given the drivers number, he responds by telling me that he had called the office to confirm the address with the sales consultant, to confirm since the gps was directing him to a suburb within the mentioned city, apparently he tried calling my mobile and also the same story told by the sales consultant where she stated sending an sms all of which i am still awaiting to reflect on my mobile. The driver never followed the gps but decided to proceed to the next location 30 to 40 kms away, simply disregarding my follow up call while he was proceeding to drive away from my location.

The delivery service is very pathetic, there is no progress status or alert sent from the order is made nor any solid form of communication with the customer. Customers have to chase up with the sales consultant before getting the drivers details since no one sends any notification or establish contact with the recipient.
