VERY UNHAPPY

On Saturday 19 December 2015 my cell phone was upgraded via telephone by a very friendly lady. I was to receive a new handset within 3 to 7 days. I have been a custormer for 16 years. A month later still no handset. I called their offices and was told that they did not have stock. No apology for not keeping me informed. The guy said he would find out and come back to me. He did not. 10 days later I received the phone via courier. I struggled for 3 days to get the phone to work, even going to the branch in Bloemfontein. Tried the sim card in other handsets it would work, they also confirmed the handset was faulty. The Monday I reported the matter to Midrand brand and they said they would send the courier to collect the phone to access it and then send me another phone. 10 days later they collected the phone after I complained each and every day. I have since then received no response. If I call I get transferred from section to section. I would like to cancel the contract but I either get cut off or transferred again. Last Friday I called Midrand branch and asked to speak to the manager. He was not available but would call me. We are now on Thursday and nothing.
