Slow service from Vlocity Communications

After just 5 months, the UPS, an essential device for my work, bought from and installed by Vlocity just died, despite all plugs having surge protection. After my many calls to various call centres and technicians and avoidance of the problem, they collected the device which effectively was faulty. I finally wrote to their CEO who invited me to their offices at Century City. The correct thing would have been to replace the device at their cost. What was the point of meeting at their offices? Another few hours of wasted time. I charge by the hour for global companies and was so desperate that I contacted Hello Peter, the first time in my entire business career that I have resorted to this platform. After the review, the CEO wrote me a rude letter, accusing me of not having had surge protection, despite zero load -shedding and telling me the purpose of the meeting was to "gift " me another UPS! If that was the case, their technicians would have brought the new device and installed it. After the review, he refused to hand over the device to a colleague who had offered to collect the UPS and had in fact paid for the entire system, unless I retracted the review. Obviously this is nonsense and was a weak excuse. He also declared that I had been harassing their staff ! The entire relationship was destroyed unnecessarily and I have since changed ISP providers.
