Samsung the worst after sale service ever

I hate posting complaints on the internet but sometimes this is the only option.<br> I handed in my Samsung S5 for the free screen repair as advertised. That was 3 March 2016, they asked me to send proof of purchase as the serial number was 2014 module and they wanted to check if the phone was not older than 2 year which it is not. I did forward that the same day, they confirmed receipt. I gave them till 9 March and follow up. You can't get through on any numbers and eventually got through to the call centre but they can not get through to the repair centre so left a message. On 9 March got a quote for the repair... so I send through additional proof of purchase. Left many massages at call centre with no call backs. Visited repair centre and manager confirmed on 10 March everything is in order and it will be a claim. Visited repair centre again on 14 March where they confirmed parts did arrive on 12 March and I should have the phone latest today. I just received a sms asking me to accept the quote received previously. Refilwe Mahlangu don't know how the reply on emails or to use a phone and the same for the rest of the staff at 14th avenue centre. I will rather go to SARS than Samsung
