no repairs for over three months

I bought 2 proline bundles a few months ago, three months ago my wife came home from work and complained her phone no longer booted, I checked and it was stuck in a reboot loop, took it to the Lewis (Steynsburg, EC) where I bought it, the manager had a look and she also saw that it was stuck on a reboot loop. After a month of no word from Lewis we finally got a reply back that because of a piece of plastic that was broken off, the phone is no longer under warranty, and that it'll cost us R275 to fix it, we were asked if we want to have it fixed, and we gave the go ahead, and we were told that we will be billed once the phone is repaired.

About a month later we were informed that the phone was returned unrepaired. The manager told us she will get everything sorted out. it's now a month later and the phone is still unrepaired at Lewis in Steynsburg, the Manager left at the end of October, and the current management of the shop has no clue what's going on.
