Absolute Nightmare

So on Saturday morning at about 06h00 my unlimited fixed lte service with OpenWeb swas reduced to a download speed of 0.50 and upload of 0.40. I tried unsuccessfully to get hold of OpenWeb, it is impossible to speak to anyone. I sen messages Via WhatsApp and email to no avail. 3 days later I get an email from them saying they have opened a ticket. No feedback, nothing. They asked for a speedtest, which i sent 4, all done over the last 2 days, all showing literally no internet at all. I work from home so I have to spend money elsewhere to get internet, my service with OpenWeb cost me R900 per month. I put in a cancellation request and low and behold they still want me stick to their terms and condition which states I have to give one calendar month, even though i have no internet. These guys are not good, at all. If you decide to go with them you do so at your peril
