Frustrating ROLL OVER

Data Rol*****!!!!! I am very disturbed by cell c. Last week I tried to roll over my daily bundle before mid night twice , the amount for rol***** was deducted twice , and no data rolled over. First I was told data only lasts until 3, any way I got a refund after receiving two answers I wasn’t happy with. Last night again , deducted twice and not rolled over. At this moment I’ve tried to roll over my daily bundle and still nothing happened, but now I’m afraid to try again cos they’ll deduct twice !! It is extremely frustrating to have to call for a roll over and get a bs explanation and to actually wanna roll over and it’s impossible.... CELL C needs to get their story straight and deduce if they rolling over or NOT! And stop wasting a 10 year clients time!!!!
