Terrible service and care for products

I made a loan against my microwave on the 19th of February they did the quality check of the microwave oven instore and today 26 February when I came to pay them back and get my microwave back I discovered that the front knob bottom holder is missing the consultant kept on accusing me that I brought it in that condition I argued that the store did a quality check before giving me the loan against my microwave when I brought it it was wrapped in cloth and they told me they will wrap it and gave me back my cloth back that day today when I came to fetch and pay back the loan the consultants tells me no they do not wrap the items and the consultant after making me wait for 30 min took my number on his personal cellphone which he could easily delete and said he will contact me when I asked for their numbers and email address he rudely reffered me to the slip and said I can send a WhatsApp which I immediately did and I gt a response of just the word ok!.........now I'm home with a microwave that is overlapping yet I paid them back every cent
