Worst Customer treatment ever

I would just like to express my frustration and irritation with this company. For months I have been back and forth with them, for my own money! I've paid them last year April, to which their agents kept logging incorrect tickets, as my fibre line was broken, I have then waited until September and decided I will ask my money back. Since then I have been told I would be refunded in 30 days. Then someone said two months and here we are a year later and they still have not given my money back! I am absolutely shocked at the service provided. There were times when agents were completely rude or couldn't even answer when asked why I would need to wait. A few of them wouldn't reply and wait for the chat to automatically end, as this happens after am hour of no communication between customer and agent.
