NO FEEDBACK after urgent request

<p>I upgraded my phone in August as this was the month of upgrade. I went online and chose the phone and package I wanted to save money by not paying an upgrade fee and having the phone delivered. I received the invoice for September which includes an upgrade fee of R150 and line rental for the new contract (R112.45) backdated to August. But in August I paid the full line rental for the package the phone was on even though I could not use it anymore since the upgrade date. I phoned 082111 on the 12th of September and asked them to log a request for investigation. I was assured I would be contacted in 48hours with feedback. On 15 September I had to phone again after not receiving feedback. I spoke to Thandi (refnr: 1- ********** 8149) who said she can see the 48hours has passed and no one has attended to this yet. She said she'll escalate it and that someone would contact me on the same day. It is now Monday 19 September and I have still not been contacted. All I want is my invoice to be recitified to reflect the cost of what I agreed to by having the line rental for August as well as the upgrade fee removed. R262.45 overcharge needs to be removed. Please contact me to let me know this is done. I am fed up with having to struggle just to get the bare minimum service one would expect.</p>
