CELL C YOU ARE THE WORST

I have been trying to sort out the last payment on my cancelled cell c contract since March. I have not once be contacted by Cell C even after reversing 3 debit orders. I have been on hold with Cell C today for a total of 3 hours without assistance. I cancelled my contract because Cell C cannot supply 4G and I was never informed of this so I cancelled the contract with a 70Gig loss of data. Since then I have had not been contacted by Cell C at all to sort out the last payment as I will not pay the full amount due to the 70Gig loss. I am more than willing to pay the rest If I could just get someone to answer the phone or to actually phone me back. I will keep reversing the debit orders until I can get some one to sort out the mess on their side. I have been trying since MARCH to get this sorted. CELL C YOU ARE THE WORST
