Complain

My mother bought a KIC fridge at lewis store at moratiwa crossing last year December, and when she opened the account they told her that she must also an insurance because she's a pensioner. So the problem started last week(18/12/2020) when the fridge stopped working. She visited the store at monsterlus, where she got bad customer service and even today nothing was done about the matter. So we contacted Lewis customer and they dropped their calls on my mom. So we want Lewis to fetch the fridge and give us a new fridge because the warranty of the fridge is still active and my mom is also paying Insurance.
