22 days and problem remains unresolved

On the 28/01/16 I bought a 1gb data bundle extender. On the 25/02/16, I got a message that my bundle was about to expire in 2 days. So on the 26/02/16 I bought R50 airtime, from which I bought a 30mb data bundle extenda & was left with R39 airtime. On the 2/03/16 I noticed that my data bundle of 830mb and my airtime was depleted. I call the call center and lodged a complaint with the technical department and was told that my query will take 24-48hours to resolve. It's been 22 days and my query is still unresolved. I spoke to numerous agents with over 20 calls and still no joy. On the 15/03 I called through and spoke to Ndumisa Magudulela who updated the case and lodged a complaint that my 1 gb bundle expired when it was not meant to and I should be reimbursed by latest the 17/03. It's now the 24/03 and still nothing. I called the call center yet again and all I'm told is that they will forward the query to the relevant department to assist. I'm sick and tired of this terrible service. My airtime and data was ****** and cell c is making no attempt to compensate. The data bundle extenda is all a hoax!!!I had ported my number to the cellc network but it seems like that was my mistake!
