BAD SERVICE

It has now been 3 weeks since I asked them for a bill showing all calls made by a number on my contract. Since today nothing. The guy is leaving my business so I will be paying all his calls. YEEEE. In February I did a upgrade on my WI-FI since then the one is not working the lady in Bethal where so help full an tried her best but with now help from her head office it is still not working. I have sent them numerous emails nothing.
