No internet. Terrible service

Rain!!!! Ive been struggling with slow to no internet speeds for months now. The matter is not getting resolved. A lady from Rain phoned me on monday and couldnt get the problem sorted. She then said to me she must talk to her technicians to find out if its the tower or my router thats the problem. She said she would contact me yesterday with a conclusion,but i still havent heard from her and am let yet again for days without no internet,she said that they will sort it out on my bill.... Im asking one last time if you could get a technician to phone me, and to resolve this matter today still, as my patience is running out. Please get someone to contact me who actually knows what they are doing, and who actually cares about service gor their clients. Otherwise im cancelling my subscription. Ive really had it!!!! Enough is enough!!!!!
