Poor service and bad attitude

On 15.07.15 took my phone to MTN in Tzaneen mall,Mr Tungwane accepted my phone,I told him that I have insurance with MTN, he said everything was OK my phone will be repaired within a week, a week went by and I went back to him,he showed some numbers on his computer and assured me that one of them was phone and it has been fixed and will be delivered in few days. On the 27 I noticed smses on my other phone which has been off for days.they were from repair center giving me a qaote for my phone,I was surprised, I then called mr Tungwane and asked him,why I was receiving this quote s if everything was fine like he said, he said \ooh are you using insurance ?"Which I answered \""I told you when I gave you the phone\"""
