Don't care attitude

I bought a tab at the mtn branch in gateway on the 28th of Sep, only to find it was faulty and damaged. Emailed mtn customer care, got a response to go to the branch of which the manager was to quick to say it has passed 7days since the purchase. Showed him my emails with customer care was before 7days. He I must leave the tab and he will investigate and call me. He never did but instead got the staff member to call me and said they will send me pics of me when I left the shop of which I'm still waiting for and this was Friday(06Oct). Still no pics or a phone call. I again emailed customer care on the same Friday and they also have not rep****. I have been with mtn for over 10years and I don't think this type of service is acceptable. To be totally ignored and disrespected in this manner. No one cares about the customer here.
