Telkom drains data

Telkom monitors the frequency in which a person buys data, thereafter use it to their advantage. Just because i buy data frequently, telkom is now draining my data in minutes. I can barely go through social media, few minutes later im already getting an sms that 1G has been used up. Its unfair, should i now have a new strategy of using a telkom sim for 1 month then throw it away and get a new one, because when i buy data frequently you keep my stats and assume im rich and take advantage of me. Even 5Gig is nothing with you guys. I spend alot on airtime with telkom im tired. My data disappears so quickly.
