Don't buy Cell C, vouchers online

I'm on prepaid with Cell C , I always purchase my airtime vouchers online through my bank, and within a minute my airtime is loaded to my phone. This month I purchased R 200 airtime, and it simply did not get loaded to my phone. I phoned the bank , who looked into the matter, and told me it is from Cell C side, I phoned Cell C , who told me they were experiencing problems, and need to be patient. But I now needed airtime, so had to go to a supermarket to purchase more airtime , cash, to load on my phone. I phoned 24 hours later, and was told the same story. It's now a week later. I'm tired of phoning each day and been told to be patient, and no solution offered, except to go back to supermarket and buy more airtime. this is completely unacceptable. I'm R200 poorer with no airtime and no solution in sight. I refuse to buy large amount of airtime from the supermarket and then have Cell C , load the already purchased airtime to my phone, and then sit with more airtime I need, that will expire..... <br> I now I remember why I cancelled my contract with Cell C in the first place... Shocking service... No solutions.
