cell c poor service

On the 13/2/2018 I recharged for R150. My account was not credited. I recharged again for R150. Again I did not receive the airtime. I contacted cell c. They said they had a problem with ABSA . I must try another bank. I recharged for R50 with Nedbank. My account was credited with R50. I contacted ABSA who confirmed that the R150 x2 went through and they tried contacting cell c but they said the customer must phone in. I contacted customer care for the 3rd time. They said they referred it to the technical dept who will sort it out by the 14/2/2018. I even send them an email with proof of purchase. until today I have only received R150 airtime. I am still waiting on my other R150 . calling customer care is useless because they cannot resolve the problem.
