Disgusting Service

I have been experiencing terrible connection issues with my Telkom wifi line. This issue is going on for over 4 weeks. My wifi connects for about 2 minutes then drops the connection for over 5 minutes throughout the day meaning I don't receive a stable connection at all in the day. I use this for work and it has affected my work drastically to the point of me receiving a warning for unable to take calls on a call app which requires data. I've had to resort to loading vodacom data to supplement what the Telkom should be doing. I'm currently paying R679 for this ******* and I've loaded over R1000 worth of vodacom data just to get my work done. I have been to the Telkom store where the consultant stated that there has been an issue in the area. I have called the customer care twice of which agents said an investigation would be launched and up till date no one has sorted this out. I've tested the device and the Sim and it is definitely the connection that is the problem. Agents have told me "well there has been a problem due to weather and other issues" so what? Am I supposed to just be paying for something that's not providing me with a service and just accept it? I'm sorry NO! I would rather cancel this contract than lose my job because I'm not receiving a resolution with this!
