Poor service and feedback

I bought a Defy Toploader Washing Machine from Lewis in November 2014, 2 weeks ago it started giving problems. On Thursday 12/02 I phoned the branch to log a call. The lady answering the phone requested the serial no, which I provided and informed me they will call me. On 19/02 I phoned again and was informed by the stock clerk he doesnt have a logged call of me. I then again logged a call and he told me he will phone me to inform me of when they will come out to look at the washing machine. After 4 hours I had to phone back to find out when the repairs will be done. He confirmed that it will be the 24th, but the service centre will contact me on 20/02 to confirm the time. As to yet no one has called me.
