Unhappy customer not having reasonable recourse.

We have from 10 p.m. received intermittent service for a while and we did report it to the salesman but he did not come back to find out if things had improved. Today there was no Wi-Fi connection. Later it returned on an intermittent basis so we checked and tested the router and modem by re-booting.Both appeared OK. When speed-test showed a much lower speed than normal it appeared that we were not getting what we have been paying for.Unlimited service at R699.00 We probably have been put into a basket of low to moderate band-width users ?? I am 72 years and unable to get to discuss this issue with anyone and after spending the morning in utter frustration I am now in the belief that I should cancel and move on ! But reading some opinion from disgruntled customers it appears that there is the likely-hood of coming away without even a fair-severance . Do you see this as good performance ? I surely do not. Did we get what we paid for ? Most certainly not !
