Takealot never call when client doesnt answer door

Takealot has a same-day-delivery service to which they charge about R120, of you pay before 11am. Today i paid for my package at 9:30am. It was extremely urgent and important that i received my package today. I stayed at the office during the allocated times just to be able to receive the package. The courier arrived and rang the doorbell to which i was not aware it was not working. They did not knock or try call me or try any other means to get hold of me. When they left i received a message from Takealot saying they 'could not deliver'. I got the message while i was waiting inside the office. If Takealot makes such an effort to keep clients informed about when it is on-route and when it has not delivered, why cant they ****ing just call their clients? Takealot have never ever called me. I dont see the relevance in putting a note to call me if my number is on my account. Its common sense to call. Seriously, Takealot, instead of your hefty same-day-service fee and your track-my-parcel sms bull****...just call your clients
