telkom mobile contract

<p>I recently app**** for a contract upgrade after being called 15 times.I then went to shop app**** with all my information.I have been trying to find out what the feedback is and was told they are doing a manual check for my credit.I I didn't have credit why did they kept calling me I feel like ending all my contracts I have been a loyal telkom customer never skipped a payment so why I'm I struggling with this now</p>
