Disappointing and Time wasters

I used to use Home-Connect and then changed service providers. I have moved places and now had an opportunity to choose a preferred provider. Based on my previous experience with Home-Connect it was a no brainer, because the last time I engaged with them, their service was stellar, within 48 hours I was set up and ready to go...I guess I spoke too soon, or I was just one of the lucky ones then because recent engagements have left me completely disappointed and time wasting. I have wasted almost 3 weeks now, between back and forth, numerous follow ups to no responses from their team. I asked them "If you can't assist me, let me know and not waste my time", guess what! They decided to waste my time and money because whilst I was hoping they would help me in a matter of days, I was buying data so I can work. Just VERY DISAPPOINTING!!!!
