Don't get a contract at Telkom. They sell your information

I'm so disappointed in Telkom with sharing my details with 3rd parties. My husband and I both have Telkom accounts and we have been receiving about 3 calls per day from a company claiming that they are calling on behalf of Telkom. The number is ***. He has also been receiving calls from this company to his work phone which is very inappropriate! I'm tired of getting these calls really! This will leave me no choice to end my contracts with Telkom. We pay about R2000 for our contracts and Telkom but looking at this situation we would rather leave because we getting these calls everyday!
