Poor Service, then again there is no service

I was promised a call back last week by Rendani a Manager after me logging a complaint regarding the service received. I say again, what is promised and what is done is the total opposite. He promised to call me back the next morning but nothing. Stull nowhere closer to resolving this apart from me wasting my time, money and energy trying to fix a ********** matter they created. Still waiting on that call. I'm really not sure how bad the service is, as there is no service.
