Shame on you Samsung SA

Does Samsung International know what is going on in SA? Four years ago I bought a fridge from Tafelberg which had to be fixed under its two year warranty. Liptronics is their service provider. Liptronics does not have a telephone st or ever pick up a call. You have to email them and if you are lucky, you will get a response. For the next four years I have had to pay consistently for the same problem which they cannot fix. They do not respond to emails and then when they do get hold of you they say oh but it’s out of warranty!!! BECAUSE THEY TAKE 3 Weeks To answer an email. I have spent hours on the phone to their call centre - who pass the buck on every occasion!!!! How embarrassed would I be if this was my company - cringe-worthy to the highest degree!!! Shame on you Samsung
