3G Nightmare

For the last 3 weeks I experienced very poor 3G speed / performance. After numerous visits to Telkom's Clearwater branch I got a new simcard and bought a new ****le at their recommendation (and my cost). No change! I contacted the Facebook page 3 days ago and got a reply there that someone will contact me. However, no contact from anyone till now. For example, the past 5-6 hours the upload/download speed hardly ever went faster than 25KB/s. The connection disconnects at regular intervals too. Is this normal Telkom 3G??? How can I operate my business with this kind of internet???
