Still no response from TFG

I filled a complaint against the abovementioned store about a phone that I bought on the 27/01/15. This was on last week already and then I received an e-mail advising that I was gonna be contacted by their Customer Services Representative and on the email it mentioned 54 hours excluding weekends. They haven't contacted me since then. The people from the store keep coming and requesting my password off which I gave to the area manager last week already. In really not happy with the service that they're rendering.
