4 months later with no solution

Good Day, I am appalled at the service and the terrible quality of the adsl line. I have been struggling to get a line installed at my place for 2 months and after several interactions and multiple technicians later I finally got a 4meg line. To this day the internet has been running extremely slowly ping of +-1000ms and it keeps fluctuating (basically I am running a 56k line). I cannot browse or anything. I have logged several requests and each time the technician comes out he/she doesn't contact me and resolves the case. The port is congested all i want is a new port and for the technician to actually call me to test the line out so that this can be resolved. Please allocate me a new port where its not congested.
