Dissapointed with Cell C feedback on query

I logged a query on the 2nd March with regards to the reception at my new residence that I took occupation on the 28th Feb. The agent appointed a technical person to come to my residence and take some readings which they have on the Wednesday 4th March. Since then I have been trying to contact cell C on a daily basis and more than once in a day as I have expressed my dissatisfaction on the feedback and also explained the urgency of the matter as when I get home I have no signal to work or do anything on the internet. My *** is the initial query. Can someone please get back to me, I am not prepared to go into another weekend with no internet service or broken phone calls at my residence. Please can you treat this matter with urgency.
