3 Months without my iphone 5s

i took my iphone 5s for repairs in Kimberly at the Diamond Pavillion mall on the 13th of october 2015 because it was not charging and not switching on. it went for repairs and it came back still faulty, with the same problem as we tested it at the store to check if it was working and it was still not charging. they wrote no fault found on the system and i booked it again the same day as it was not fixed on the 23/11/2015 with ***. i got an sms that my phone was ready for pick up at kimberly and in the same week i got a call from a lady from head office asking if i deactivated the find my iphone feature. i asked how can you ask me that when im supposed to collect my phone and she told me that my phone was still not fixed. i went to the store on the 31st Dec 2015 to check if my iphone is back and i was told that nope its still in for repairs even though i got an sms to pick it up. today is the 20 jan 2016 and i still dont have my phone. i'm starting to lose it now as i'm still paying my monthly subscription on time even though i'm given this terrible service from telkom. so can someone please sort this mess out.<br> <br> Regards <br> <br> Neo Majeng
