Poor Customer Service

I handed my phone S3mini for repair at the Bolders Telkom direct Store on the 24 March, I was informed that I will be updated via SMS . I am yet to recieve any feedback , called 180 last week and was told phone is at the repair centre . I called 180 again today ,spoke to Cona who said customer care cannot follow-up need to call the store ,I was given the store number which rings with no answer .Now who do I follow-up with ???<br>
