Telkom adsl - no fiber - stay away

So I was on a 10mb adsl line and after numerous items logged and technicians which was sent out I was told the best speed my area will ever get is 5.5 -6mb doenload speed and my average speed test normally round about 4mb. So after complaining and basically insisting that they are sort of *****ing from me as I paid for 10mb line and they provide a 4mb line. The only advice they could give me is that I must downgrade to a4mb line again and the technicians told me that I would get close to full 4mb download as my area where I live could only go to 6mb. So after concideration this was done and since it was done I only get download speeds in evenings of 1.5mb to 2mb download speed. I am so frustrated as none of my streamimg is working except for the dstv now and show box **** which telkom has a partnership with. So today I wanted to go back to my 10mb line so I at least get download speeds of up to 4mb again but I was told that my area does now mot support this and they Cannot help. I have now logged another item with telkom which will probably also not be resolved for speed. They will probably tell me the best speed i can get from exchange in my location is now 2mb.. it seems that items never get resolved and it takes forever. My advice will be to stay away from telkom unless you have a fiber solution in your area. It seems that if you are on 10mb line you only get up to 5mb line and if you are on 4mb line you only get 2mb if you are lucky. Well it feels as if they are steeling from me in that sense. I know now that they previously confirmed that best doenload speeds in my area should be 6mb. So now that i am on a4mb i should receive 3.5 to 4mb the whole time... well thats what i thought...speed test every evening for last 3 evenings 1.5mb to 2mb. Very dissapointed client... aweful to wait on 10213 and 10210 services and they cant transfer you of one department cant help you.
