Pathetic service from Makro

On 23 September I ordered and paid for 2 books that according to the online shop is in stock and would be delivered in 2 to 5 days. I followed up on Friday and they promised delivery for Monday 30 Sept. On Monday I phoned as nothing was delivered and the telephone agent informed me that they will get back to me. Needles to say I received no reply from Makro. I called again this morning and again the agent informed me that they will escalate and call me back before 12h00 today. Again no call from Makro. At 16h00 I called again and the agent said they are closing at 17h00 and that I should wait till tomorrow to hear from them. I demanded to speak to a manager and she assured me that management will call me by 17h00. I knew this was just an answer to get rid of me. Again no feedback or courtesy call from Makro. This is the most disappointing service I have ever encountered. These books were meant for a pupil that started school today. I am disgusted with the service. Maybe Makro's Management should ask Takelot to give them some pointers or even training on customer service.
