Damaged phone

I booked my phone for repairs on the 18th August. I waited for the promised 21 days,when it elapsed with no communication I decided to make a follow up.on the 8th September I was told that my phone was dispatched to the store in mall of the north. I have been to the store 3 times,twice I was told the technicians are off,the 3rd time the technician told me Telkom does not communicated with clients unless if it is to say the device is back.As if that is not enough last week I went to another Telkom store to ask for the contacts of the repairing store with no assistance.It's been two months now.
