Complaint and query about delivery . Distasteful customer service

I ordered a device with Take a lot on the 2nd of June 2024 and it was set to be delivered on Friday the 7th by 17:00 . I put my work address as a delivery address and because I knock off at 15:00 I had to sit and wait till 17:00 to receive the device since I had made a commitment but funny enough Take a lo did not even think of alerting me or updating their system that I will not be receiving my order on that day , no one even called me which I then left . Then I received an sms saying delivery was rescheduled for Monday the 10th of June 2024 I then waited until 15:00 then decided to call them on *** and spoke to the first guy who didnt say his name and he promised to schedule the delivery for 16:00 at 16:00 I called and spoke to Amy who said she would call me back after checking with the courier company and she never got back to me . You would think that since it was set to be delivered on Friday it would be prioritised in Monday but clearly thatynot the case because I left for home without getting a call or an update . At 18:15 A guy who said was the driver called me to say he has the parcel and would like to deliver at the business address at 18:15 ? He then said he would do it the following day and the following day I got an sms saying delivery is set to be done on the 12th of June which I find so disrespectful and disappointing because why the hold up ! I called an spoke to Marche and she promised that they did a same day delivery for 12:00 to 13:00 today however I am still waiting. I di not know who to call or who to escalate this to as I have already tried three times to get this . I have paid R4498 for this and do not expect to be treated like this . I hope everyone is made aware of such an inconvenience and will think twice about ordering especially expensive stuff with Take a lot
