Still waiting

I bought a Huawei Mediapad T1 8.0, 2 weeks ago that comes with a promotion of free MWEB Wi-Fi until the 31st March. I cannot access free MWEB wi-fi since i bought my tablet. I logged in a call on the 19th of Feb and spoke to a consultant who said someone will give me a call regarding this issue. No one phoned me then I also logged in a call on the 20th to follow up. This time around the person that I spoke to did not have a clue of what I was talking about, was transferred to someone else who also didn't know anything. Really disappointed with the service since no one has come back to me to assist me after I had left my contact details and those answering the calls do not have a clue of what I'm talking about.
