Non existent / inept customer service

I purchased an oven/hob combination for my tenant. Makro does not do cubpboard installations in kitchens. I contracted an external company to install the cupboard. They slid the oven in, connected it and it tripped the breaker immediately. I then TRIED to log a call with Makro to send their guys in to do the electrical installation and fix the problem. This is where the problem started.

1.) Tried to log a call via phone, they asked for my invoice number. DESPITE MAKRO HAVING THIS DETAIL ONLINE as promised by their sales guys when I got a card.

2.) I then had to go in to Makro and print out my invoice, I took it to an assistant on the floor, in the appliace section, who told me he knew what exactly what to do. Took my details, TOOK MY INVOICE and said the support guys will call me the Monday. 2 weeks later, no call. I did not receive a log number or incident number, nothing.

3.) I have to go back to MAKRO, AGAIN, to get my invoice printed out. This time I call again, with the invoice number to explain the problem. They pass the buck and tell me to call the store.

4.) The store does not answer. Impossible to get through. I will have to go in AGAIN to MAKRO explain the situation. its been months now and my tenants oven is still not working. I can only say this will not be a pleasant experience for the poor staff that will have to deal with me now.

I am ready to take this to small claims court if I do not get assistance in this matter, this was my first purchase from MAKRO, and it will never, ever happen again. Stay far away from this store. What makes this bad is that i made this purchase IN STORE. Not even online. The level of incompetence and bad customer service for this place is astounding. It borders a ****.
