Tech5 fibre

I am very disappointed in tech5, today I woke up with a debit order of R929 on my savings account, I signed up for services on the 25th of January but a technician only came to set up everything for me on the 30th of the January and told me someone from tech5 will call me and give me my password, no one called I had to google their number and ask for my password, and that’s when I started using the service, my initial plan is pay at the end of the month (pro rated), to my suprise today I got double charged, I called tech5 and they couldn’t give me an explanation and told me that the minute I sign up for service and is me being active even without using it, I’m very very disappointed and hurt and being given the go around when it comes to explaining the charges
