Don’t take emergency airtime from CellC

Bought R70 airtime from my FNB cellphone banking and paid off my emergency recharge airtime, think I only owe R1.50 Got an sms from CellC now saying I owe R62, I have screenshots of the sms and bank transaction. Please update my details and stop sending me messages that I owe you. I have had many issues with CellC towards the end of last year with not getting loadshedding data when I was often buying R25 daily 1 Gig data and now you just want more money from me
