Disgusting Cell C ! Disgusting !

I am so disappointed in Cell C , their service and product . My airtime of R106 was taken from my account during the night . This occurred because night data I had was not used during 12am -5am , they instead went ahead and took my airtime instead . I called to enquire on it, I was told that it would be refunded . A week later , today , I call and am told that the airtime will not be refunded as there’s nothing they can do . They mention that some of the data was refunded , an SMS was sent - it was not . I asked the agent for proof of the airtime being refunded . She put me on hold for 7min only to come back and tell me they cannot prove to me that the data was refunded . How awful !
