Condescending Attitude from a Manager

My Name is Tebogo. I bought an Aluminum Door at Leroy Merlin, Little Falls Roodepoort Branch. On December 19th 2020 i went to collect the door. It was loaded on the bakkie and I headed to the North West where it was to be installed. When i arrived in the North I realised the door dispatched was the wrong door. I had made countless explanations to the sales person what type of the door I wanted similar to the one they had on display. To cut the long story short the following day I drove back to joburg with the door to Store. I was assisted by Disebo to change the door to a correct one. It turned out the Store had an INCORRECT CODE on the display that's why there was a mix up. Now this mix up cost me R3700.00 through a rented bakkie and fuel. I mentioned this to the Store and I was told a Manager will get back to me on Monday 21st Dec. Two days went by with no response. On the 24th I called the customer center, I was called back by a guy telling again the Manager would call me in the new year as he was already on leave. Interesting one then, in the new year i called the store - 14 January 2021 to be exact. I spoke to Anna who promised a manager with call me back shortly. I received a call from one Sebatian (Didn't say his surname even when I asked). He told me i should be grateful the store called me back but there was nothing the store could do further since i have the correct door. I suggest I return the door to the store so they deliver it to the North West, he said that's not possible. He further said I should come and BUY something at the store that's the only way they can do something, by discounting what i buy. If this is not condescending I do not know what it is. Horrible Conduct if you ask me!
