Unhappy bad service

My Samsung A3 cell phone could not switch on. I handed it in for repairs (under warranty)on the 13 November and was told it would take 3 days to repair. I haven't heard from them since, not a sms nor a phone call. I called in on the 18th November to hear that it could not be repaired and was going to be escalated to Samsung Head office. I called in again on the 20th November and was told the device was repaired but failed quality check and new parts were ordered. After the 20th November the phones seems to be down. I visited Samsung on the 27th November and was told by the manager that the parts have just arrived and if I could wait it would be repaired. I waited for two hours. The manager seen me waiting and never updated me once. Today I received a call from customer services wanting to know if I was happy with the repairs done to me device, I don't have my device back yet and I am left inconvenienced without a phone. is this what Samsung calls service? Very unhappy client. not happy buying Samsung products going forward. The reference number given to me is ***<br>
