falls reporting

For past 2 months my phone was not working, reported it several times without any thing being done. Last time I reported is I received an sms to notify me that everything is back to normal. The technician came and said he willcome back as the problem is not solved, but then im receiving a messmessages that everithing is fixed. I reported a matter again with an exchaltion number given as a reference but still nothing is happening. #ref 412ctz031115 exchalation # 779502
