Received printer back from repairs damaged

I bought a HP printer in February specifically for the purpose of printing assignments. The printer was used once or twice and it worked perfectly. About the third time it no longer printed black font properly thus it no longer served its purpose. I took it back to Makro in September with my till slip and it was sent in for repairs. I collected the printer and was advised that the cartridges needed to be replaced. Firstly the printer was hardly used secondly the printer status screen on my computer indicated that the cartridges were three quarters full before I took it in. I begrudgingly accepted that I had to replace the cartridges even though I hardly used it. I arrived at home and found scratches on the printer, I went back to Makro and they advised me that they would send it back to the repair centre. They contacted me about 2 weeks later and when I collected the printer I found that there were still scratches on the front apparently they only replaced the top cover. The manager that assisted me told me that it is not their fault, it is the repair centre. I am annoyed that the printer is faulty and when it was received back from repairs it was not in its original condition.
