No feedback in over a week.

I have been experiencing intermittent connectivity issues with my internet for almost 2 weeks now and it is affecting my ability to work as I am working from home. I have logged a call with SADV Ref No SA190287 over a week ago and still to date I have not received any feedback and I am still experiencing the same intermittent connectivity issues which I still have no explanation for. I am very disappointed in the service I have NOT received from SADV and really need some feedback whether my issue will be resolved or not so I can decide whether to move to another ISP or not. I hope to get feedback on this complaint if that's not too much to ask for.
