bad customer service and a disrespectful manager

I bought a washing Machine at Hifi Corp Carnival Mall and I was assured that I would be able to collect it at any of my nearest branch once I'm done paying off the lay-buy. now I'm done paying the lay-buy (which I was buying it at South Gate Branch) now I am getting stories when I need to collect. the manager at Carnival branch (Calvin) was so rude to me on the phone yesterday telling me he doesn't have time for this, when I was expecting him to solve this issue for me.

I'm surprised that a brand that I trusted so much now doesn't have time for me when I need a product that I paid for with my hard earned money

now I am stuck and don't know how I will get my washing machine that I have paid for.

The disrespect from the manager has ruined my relationship with the HIFI CORP brand.
