Sent in Huawei Mate 7 Gold for repairs

I sent in my brand new damaged Huawei Mate 7 Gold to Telkom Mobile store in Centurion Lake Mall for repairs. After a long wait of almost two months the phone was returned on December 31, 2015, However, Telkom returned a wrong unit to me, the unit has less technical specification than the Gold Mate 7 I entered into contract with Telkom. I raised this matter sharply with Mr Clint Bagley at the Store but he insisted that I should take the phone since I was incovienced for the past two months. I wrote to Mr Bagley and went to the store as a follow but in vain. The store manager Ms Gangen promised me that she'll follow up the matter with Huawei South Africa but to date both Ms Gangen and Bagley hasn't called or write to me again. Next week will be end of January 2016 without any traction on my case. The Gold Mate 7 had 32GB of internal storage, 3GB of RAM and It was a dual sim and the unit returned to me its white, 16GB internal storage, 2GB RAM and its a single sim. The disperity pertaining to technical specification is ernomous but I am still honoring the contract with less service from Telkom, This is completly unfair......
