Dishonest Poor Service Network

Very dissapointed , got the 60GB offer of February 2019 and everything was fine up until beginning September, got 29GB and paid R199 every month on something i never used.so i went in and enquired and only got a sms with a case no that till this day has not been responded to, also this morning new data was suppose to be loaded and got HALF of the initial GB i signed up for. Why would you advertise this deal if you knew you wouldnt be able to supply.
