Vodacom polokwane(limpopo mall)

I took a phone last year to vodacom limpopo mall polokwane for repair.my phone screen had turned yellow on the botton so but i could still see apps and use the phone.when my phone came back i the front camera was no longer working i took the phone back immidiately.they took it but brought it back with the same problem.i then took it back again and they were now taking me from piller to post.when i go there they will keep me unattended sometimes they will just say the person who suppost to attend me is nt available even when they are the ones who told me to come!the cover phone is smashed i believe it was whenm nt they tried to fix the said camera!!!m not happy and they are still taking me from piller to post
