Disgusting service

How disgusting is your service. For months we have been trying to fix a problem with no luck, my mother in law said she could only afford R1100 which quinton agrees he quotes ect and we take it, now we paying R819 for a 20/2 thats is shocking we were quites R682 and we getting billed R760 for unlimited calls for the month when 5 phone calls a month get made and Quintin our sales rep just ignores our calls then we get a number for hes boss Brendan who hasn't even bothered to call us back, Quintin tells us 3 days ago he can change what we need but hes laptop is running slow he will phone back 3 days later after countless of ignored calls he tells us he has had to send our request through to a specialist sales person who is the only one who can change it, what bull**** to just removed the R760 unlimited calls. You phone the office they tell us only Quintin can change it. How disgusting is this service, 10 months and a problem still isn't fixed. Nobody bothers to answer there phones or get back to you
