Jet head office need to do there work and not just getting the salary for their job

In January I notice on my account there is a R78 debit against my account for 115airtime and 100sms.I checked my e-statement for the last 10 months and I noticed there is a R78 going off against my account.I phoned jet customer care to query about this R78. They said I register for in march 2019 and that I get the airtime 100sms every month.I have received no airtime and no sms.I ask jet to refund my account because I have not received airtime or sms.Jet declined the refund because there is a reconding.I have requested that they send me the voice recording.(x2) everytime there is a error on the file. Someone somewhere is getting free airtime and sms but not me.I went to cellc to if they can see if my cell nr is receing every month R115 and 100sms they said no there is no record..It is the 4th of February and no feed back.Jet head office need to do their work and investigate in this matter and not just getting the salary.I think people are lazy they just want to receive the salary...….
