Shoddy and slow

Initially a rather shoddy setup, the installer just plugged me into the copper line without much care or neatness, thankfully I've worked in Telecommunications so I could rectify his workmanship, multiple times I have been overcharged, as of the 1st of April I have been sitting without internet, supposedly it's an openserve issue however people in the same street as me using the same exchange have never had this issue. Not to mention that the 10mbps line that was promised never lived up to its agreed upon speed, seldom even scratching 7mbps on multiple speed tests, since the 1st I've experienced nothing but excuses with no potential positive outcome nor alternative solution for the interim. After 6 days I think it's fair that I called it quits with this lot, this is no way to treat a consumer. And making internal issues the customers problem is just straight up unacceptable and unprofessional, yet seems to have become the norm as of late. Get it together.
