Service complaint

<p>I upgraded my 24 month contract for a Sony Xperia M4 Aqua DS. While still under guarentee, the phone stayed on start up screen and wouldn't turn on or respond to anything causing the battery to drain quickly. I handed the phone in at the Swellendam CellC store, where I bought it, for repair on the 15th of April 2016 and it's been more than a month now and all they tell me is that the phone has been send to Sony. Being a loyal customer of CellC for more than 10 years I feel that this is real bad service. After years of excellent service, what a disapointment!</p>
