Frustrated Client

Greetings, am so frustrated, it seems like my problem will never be fixed, last Sunday I logged a call, then it was solved the next day, only to realize that technical problem was never completely fixed, I can't sleep, this router is making lot of noise like a fridge, it has stopped working, I even logged other problem with the connection before this one happened, and am still waiting for my dstv decoder plug from technicians since Wednesday because they cut that plug cord, when they came to fix the problem previously, since they took the plug and never return, Am without dsutv nor wifi again, this is torture. I logged a call around 12:35 only to be told that they will be coming today without letting me know, and I was out from home. Why you tell me that the technicians are coming when a call, no guys stop playing. Kindly come and fix this problem because I won't sleep again the next night with this noise coming from the router and please bring back my dstv decoder plug back. This is torture
