Data exploitation

I have an existing contract with Telkom for 10GB for R139, for the past months my data would finish within 3 days after i receive the data and before the lockdown the data lasted for 3 weeks. I have a prepaid number as well, on Friday, 7 Aug I purchased data for R 69, today 9 Aug i receive an sms that data is depleted. Telkom is exploiting us with this data and they are not providing real data for the value. I have data finish within 2 days? I demand explanation as when i call your call centre there i s always no answer. You rob and exploit people and your service is useless.
