Data stick not back from repairs 2015 Apri to date

My name is Alina Nkoapho. My cellphone number is *** Email address is : [Email Removed] 12 of March 2015 I bought myself a Telkom data stick at Trade Route Mall. The stick was not working so I called the call center helpline and i did not receive any help at all...I was shocked with the level of service i received they are not well trained and know nothing about Data. On the 4 th of April i went back to the store and complained was told that 7 days has passed and it needed to go in for repairs. I was told i can only collect i after 21 working days. After 21 days I was told that the stick was still with repairs, on the 2nd of July. I was told that they not sure who has signed for the delivery of the data stick because it was delivered but not at the store!!!The lady by the name of Zanele who refused to give me her full names but gladly gave me the 081 180 number and told me to lay a complain. I have been contacting Telkom via Facebook and each time I am told that they will get back to and they never do...May kindly assist me in getting the stick that I have fully paid for and have never used/received.
