Makro- Unprofessional and poor customer service

This is the second time that this has happened to me. I ordered goods from Makro. Different delivery dates were given. However the first 3 items were delivered the next day although the delivery date was a few days later. I appreciated that. However, for the main item that I bought, I was initially told that it would be delive5by 31 August 2026. Then I received an email that it would be delivered by 25 August. When the item was not delivered, I forwarded the email to customer services. I was told that they were working on it. I followed up with a phone call. The agent told me that the promised delivery date was 29 August. When I aske why I was sent an email that it would be delivered on 25 August, she couldn't answer save to quote me their delivery policy. I questioned why, if that was the policy that I was sent an email reflecting 25 August. She reverted to the policy. Furthermore, she referred to me by my first name. I told that that she could not do that unless I agreed. She indicated that all customers were addressed by their first names. I told her, this was not professional. In summing up, Makro did this to be before. After I submitted a review on Helopeter, the item was delivered the next day. This is absolutely poor and unprofessional customer service
