UNPROMISED FIBRE LINE SPEED & HIGH BILLS

Saturday 24th April 2021 Vodacom technician fitted upgraded Fibre Router & I called the next day to complain the line speed is still unchanged at 10mb instead of 20mb line speed as promised by the Sales Department on 26th March 2021 & are still awaiting a callback to sort this matter. Since then I have made almost a dozen calls to Vodacom Fibre Department, every time they promised to look into this matter or that someone would call me back, I am still waiting, despite asking the Head of the Department to call me. I've also been billed much higher than the agreed monthly subscription fee. Hopefully someone at Vodacom Head Office would give me a call as I called their listed landline number which continues to ring
