Ridiculous online support

Poor online service. I placed an online order on 29 November 2023, they attempted delivery on 1 December which failed. It has been a nightmare ever since for an attempt of redelivery. Had to call them non-stop to ask when redelivery will take place, eventually received an SMS on 7 December to say WumDrop was on route. Next moment I received an SMS to say my order was delivered??? Signed by a "Thato Mo***eng" who I don't know from a bar of soap. Not one person is willing to assist and explain to me what is going on.
