I've been using this same provider for the past few years - it's the first and only provider I've ever had.
There are several more on the market, but this one is the biggest, and yeah, I believe it's owned by an oligarch, but it provided great services.
However, about an year ago I started having problems with connection. First I couldn't play games online (over summer breaks I tend to do that a lot), then I couldn't download properly, after that Youtube went out and now I have problems opening wikipedia.
It just dies on me from time to time. For example, last 2 hours, perfect connection. 6 hours before that? I couldn't use Translate for 3 words.
Tech support has been coming in more than a dozen times now, they changed a lot of stuff, I changed parts of my computer, but it doesn't help. I have my theory what the cause of the problems could be, but these tech guys got fed up and tired of me and don't have much patience anymore - on one hand, I don't blame them, on the other, they should do their f*cking jobs.
They are coming again this Monday. I'm not in Leskovac anymore, at least not most of the time, since I'm studying in another town (where I'm using the same provider and have no problems), so I won't be home when they come, but I hope they finally fix it. They exhausted almost every possible cause for problems, only one or two things left.
All that said, I have, in theory, and outstanding deal - cable + ultra fast internet for a very small price. 2 year contract.
Too bad it doesn't work.
