Bad service and signal

On the 8th August we as the residents of Windmill park ext 17 Boksburg, we lodge a complain about the vodacom signal (ref# A7-UBKF-L5U5) up until today nothing hasn't been done and some of us are loosing business due to this signal issue. If plea with you to attend to this matter ASAP otherwise you will be loosing customers as you have already lost some of them to the competitors. If this is not rectified by the end of this week, I will be cancelling my contracts with you. I called earlier today and was put on hold for 22min 32 sec then she just hang up.
