Telkom only talks

Been with telkom on a landline for as long as I can remember and 2 years back in May I had decided to take out an ADSL deal with them, so I went ahead and took out a 4mbps uncapped line. Line worked reasonably okay for the first year, although I only had good speeds through the first couple of months. Over the last year I've been having a headache with them, my landline and ADSL line will randomly stop working completely and I then have to go to a neighbours house to use their landline to call telkom as my line isn't working. It usually takes a technician 3-7 days to actually come out to me and assist me after calls and calls of queries. This week, my line went out on Saturday afternoon, I had called Telkom Monday and yesterday to find out what was happening and on Monday they had told me that it's an area problem and they're working on it however they cannot give me a turn around time. I had called back yesterday which was Tuesday and they had told me that they have managed to fix a few lines but mine is still amongst those that are not working. I've also experienced problems whereby my line itself dropped to a 2mbps line as telkom says they had some network change and I had to call in to have them put it back up to a 4mbps line and this change was done without my permission or knowledge, I had only found out once I ran a speed test and discovered that I'm only getting 1.7mbps. From the start of my ADSL, I have only been recieveing a 0.2mbps upload speed which hasnt changed at all in these 2 years and thats disappointing. I am a campus student who is now on holiday and a cannot correctly attempt assignments because I have to wait for my service provider to continuously fix problems I shouldn't even be having. This is an ongoing problem and I've experienced it atleast 8 -9 times over the last 1 year. I pay my account on time and if telkom can't keep to a simple task, they should supply me with a sim card that has uncapped data so I won't lose network or keep my account as in and cut costs for wasting my time.
