Almost year still no service but taking my money

Useless useless. I've had issues for close to year now. Nothing gets done except my money gets taken. I'm sick and tired. I've been paying for a 4mb line but now not even getting 2mb. "Furrel" from telkom phoned me on the 22march and I was fighting with him about my line. He then said that he would push my line up to 5mb and that I then would get at least 4mb. He assured me that he would phone very next day. 6 days later and I have less than a 2mb line. Cant watch TV because I'm streaming. No call back and No service from telkom. But hey I got my statement already showing what I need to pay. Telkom wake the **** up and do what you getting paid to do. I will be blasting this in social media as well as emailing telkom director and ceo. Got their emails from someone that also had to go the way I have to go now to get it resolved. Also want a credit.
