Disgusting service

Disgusting service. My wifi was offline for 4 days, on the second day technicians came out, just came to check and left, no feedback nothing! It takes forever to get through to an agent on whatsapp, despite that, eventually after messaging on Instagram the Monday they sent another technician out, bare in mind that i work from home and i needed to work those hours back!! I was advised id get a refund, first agent advised 10 working days, second agent advised 14 working days, last agent couldn't event pick up a refund that was processed, the audacity to ask me what the refund was for like there's no notes or paper trail on the system ! Eventually finds it and tells md I'll get an email once its approved. I work in customer service too, how does 3 agents get to advise 3 different refund processes and when requested to escalate to a manager the story just changed, last message on insta was read and no response!
