Telkom doesn't respond for more than 3 months

On the 13th May 2015, I complaint of poor signal in bothasig was logged with the reference number 168 999 35 with Vernon (a telkom service center staff). On the 26 May, I had not received feedback and called again to escalate the complaint with Nomlungu (another telkom service center staff). Until the 1 July I had not heard any response from Telkom with respect to my query. Telkoms hello peter support staff (Boitumelo) responded to my post on the 1 July to assure me that a technician will come out to assist in the poor coverage in the area. I have not heard of Telkom since. This is an important issue as it is more than one device now!!!!
