Unhappy customer

I took out a new contract first time customer on 10 May 2018, they issued me with a faulty device. First contract was canceled and It was replaced with another faulty device and now I am waiting for the cancelation to take place. Almost 2 months later and the "manager" which it was escalated to did not get back to me with a resolution to my query. In the mean time I am also billed for both phones and I only have one broken one . How's this for some Telkom *******ion.
