Fourth time sending in my Blackberry

Good day<br> <br> I have now sent in my Blackberry Z3 for the fourth time on 15th April 2016 and it is not even close to the end of my contract. I am really disappointed and appalled as the last time I sent in my blackberry Z3 CELL C advised me that they were going to giving me a brand new phone however I received the same problem as the previous 3 times before this i.e. the charging point stops charging the phone and by the time I take it in to Cell C ,the phone battery is already dead. I am unable to save my contacts or data on my phone , by it going into repairs again I have to start from scratch with certain data which was saved but not wiped off because I sent it in. <br> <br> This time round I refuse to have a BLACKBERRY Z3. I think it's best I get another brand as I simply do not trust the Z3 anymore it is a very unreliable phone. <br> <br> Considering the unnecessary anxiety this has caused me I would like to have this phone replaced with Huawei P8 Lite White Phone for R199 per month.<br> <br> Kind regards <br> <br> Algene Anderson<br> <br> <br>
