Angry customer

Friday morning around 6am I uploaded an emergency airtime of R25 where you repay after use.. I never received that airtime till today which is Sunday and when you call them asking what to do because buying a new airtime will only pay for the emergency airtime which was never received they will only tell you to wait and not buy airtime until the problem is fixed. Which means I cannot even use my phone and today is Sunday still no feedback from cell C or the emergency airtime and buying a new 1 will go towards the emergency airtime. Yesterday Saturday I called and spoke to Andiswa, I asked her to put me thru her manager she told me she was on a call and will get back to me. Till today I have not received that call from manager Busisiwe Mange to explain to a concerned customer the way forward. Cell C is ****ting on us customers and I'm beginning to think they failing us for god sakes I have 2 contracts with them and 2 insurances and 1 router reliable paying customer but they never seem to dissapoint me every time I feel we getting somewhere with them...... I'm so angry
