Sell Direct Marketing

Sell direct/Telkom liers. I use to have a contract of 10GB for R129 per month. Plus R20 for a multi sim card. Total R149 They phone me asking me if I'm interested to upgrade. For an extra R20, they will give me an extra 10GB. Meaning for R169 I will receive 20GB of data. Was a lie. I'm paying R169 for 10GB. NOT R169 for 20GB without the multi sim card. The "upgrade" cost me R40 more for less. What a rip-off.
