Bad service

I took my fone in to Vodashop on Monday last week. Faulty battery, the battery was swollen so mich the back cover popped open. When my phone eventually got to George repair centre, it keep on saying the phone is in assesment. I have been trying ro get hold of George repair centre they simply do not answer their phones. I phoned the Vodashop in George they said they are not allowed to give the cell number of staaf, they will ask them to phone me, well this was last week I am still waiting for a call, on Friday I phoned again to get an email adr, sent an email still no reply on my email. This is absolutely horrible service from such a big company.
