Incorrect amount of data allocated to my account

I had a Wifi 10 gig sim only month to month contract. I then choose a September big deal which offers R30 gig day and 30 gig night. I received an sms that my order was confirmed I received 6.66 gig data in September but only 20 gig day and 20 gig night. I tried contacting the call centre, chatting to an agent on the Telkom website, utilising the Whatsapp number and eventually contacted an agent on Facebook messenger and received feedback that there is a problem loading the additional 10 gig so i will receive my data in future. I still have not received the 10 gig day and night data.
