yet another bad experience

This is now the second time musica has failed dismally with the warranty goods. 1 month after taking in a polariod tablet that we purchased late in october 2015 we have still not recieved any feedback. I went in to n1 city late in december and the lady assured me she has sent it in and that she will phone me. 2 weeks later still no one has bothered. Today when i went in new staff and no onr had a clue, now yet again i have been shown the door and told monday, monday we will know. I am tired of waiting. I am tired of musica and their lack of customer service. Last time we bought a vita it worked for a day and screen went dead took you guys 3 months to of phoning begging to get a new one. Totally unacceptable i live in brackenfell and have to drive to the n1 mall just to get a sorry i cant help. This is pathetic. This shall be the last purchase i ever make at musica not just this mall but any. Sort out your ranks, customer service is key and you have failed dismally yet again
