Really Bad Experience

Our experience has really been not the best. We advised our original ISP that we will be switching over to another ISP month end, only to find out that Amobia requested the line two weeks prior to the original date. This left us stranded without internet, so we had to move fast to get our installation going. On Monday we had it installed and we thought okay wow, this was done swiftly. After they left, the 1gig line was so unstable and horrible. Having to run two businesses from home, it was EXTREMELY difficult. My husband ended up spending 2 hours on the phone with a tech to still have it faulty. Day 4, they sent techs out again to see how to configure the line to run its original speed, only to be advised that it is our equipment who isn't capable of running that speed. Now I have the equipment which can definitely run that speed. If the equipment is plugged in directly with the line, it runs fine, but as soon as I run it over wireless, it is unstable. How can this be my equipment? Okay so besides all this, we then requested to please cancell our services, as we losing loads of money at the moment due to this (and I am not talking about pocket change) Only to be advised we now have to pay over an R1000 to release the line (oh and they wanting to charge us for the technician having to come out to work on their own equipment).... How is this even legal? I am really speechless... I would highly recommend their technical support team for trying to assist (and being open and honest), but would not recommend their management who doesn't care about the problem but rather money and shifting blame to equipment instead of their own technology.
