Pathetic service provider where support is concerned

I'd like to share my horrid experience with this completely ********** fibre provider. Firstly,you as a client are technically forced to communicate any issues via WhatsApp and their response time is atrocious. Today I ended up waiting over 4 hours for a response. After threatening with a hellopeter report they could quickly reply with a bot response saying they have high call volumes.you as a client never get a reference number for communication, no name of call centre agent,NOR will you see blue ticks indicating messages read.i requested my service to be canceled so I can move to another ISP.THAT message was sent at 3pm. It's now 7pm and still no response.their support is bad,matched by their service. Constant buffering when streaming videos as small as 400mb with a supposed 20mbps fibre line.STAY CLEAR OF THIS ISP!!!!
