Incompetency at Telkom Higheld Mall

I would like to share my horrific experience at Telkom Highveld Mall in Witbank. The manner in which they undermine customers is disgusting. There is no customer service. I went to the branch at Higveld Mall in Witbank to complain about my contract with Telkom. I took the 20 GB daytime data and 20GB night time data contract for the special of R 299.00. They violated the contract and charge me R 499.00 per month. This is unacceptable and a gross violation of the Consumer Protection Act. After waiting for more than one and a half hours in the very long line, I had difficulty in explaining the fact that I signed a contract for R 299.00 and they are charging me R 499.00 per month, I was treated like it was the first time that i signed a contract. This was really rocket science to the very *********** and unhelpful consultant. She promised to come back to me, Two weeks have passed and I still have not heard from her. After two unsuccessful attempts to speak to the manager, I decided to write to the manager. I handed the letter to a consultant, and up to now i have not heard from the manager, not even an acknowledgement of receipt of the letter. The manager's behavior is a gross violation of Telkom's promise of excellent customer care. This is unacceptable and a slap in the face of Telkom's noble objective of making customers smile. This is a gross misconduct and bringing the good name of Telkom in disrepute. This unacceptable behavior is a reflection of the low s**** levels in Telkom. Please help me to resolve the problem
