No Connection and no assistance from Telkomn

I recently took out a contract for uncapped Wifi via a router and I have had endless connection issues since the beginning of the month. I reported the matter on 11.04.2019 and was advised that a technician would call within 72 hours to assist. I called again on 17.04.2019 as I did not hear from the technician and was advised that my cell phone number was captured incorrectly and that he technician could not get hold of me. I provided my correct contact number and still no response. I called again on 23.04.2019 and still no response. I am paying for a service that I am basically not using. I am disgusted and disappointed at the level of service received from Telkom.
