FAULTY DEFY MICROWAVE

I bought a DEFY microwave at the opening special on 30 June 2015, after using it for only two weeks, I discovered that there's electronic buttons that does not work, I took the microwave to the store and since then I'm without a microwave, there first issue was, I had to wait for the agent, then after two weeks the agent arrived, and now I have to wait for a part to be order, but the microwave is still in its box in the store, and it's now way over a month almost 2 months, this is totaly unexceptable, this is a new mi***ave I have been using for 2 weeks and now this DEFY microwave needs repair within the 2 weeks of use, what's going to happen for the remainder of this DEFY microwave warranty, more and more problems, if we start of like this.
