A month for a reply on a call

I phone the call centre in the beginning of this month with cell service problems and they only logged the service request 2 days later???? Then they said its a 72 hour waiting period???? I did wait 4 days phoned again and then they said its 72hours only to deal out to the technical side then they will get back to me so me and one lady very nice on that side tried a few things even a sim swop and still nothing. Then i left it because im fighting a losing battle people telling me they cant do anything. Then today a guy phones he wants to send a technician to my house for a cellphone??? Ok but tomorrow they are giving me less than 24 hours notice after ive waited olmost a month. This guy got cross with me and wrote things on the computer and i phoned call centre again and said this is the situation what now no she will add a note on monday 14:00 they will come then i phoned again and the other lady said they cant do that and this and that. I have had enough now is this the service south africa is giving people these days???
