Cell C just makes promises

I posted a review on 31 Dec regarding the no/poor coverage. I signed a contract 4 months ago and have since then been reporting this issue. My mom -who uses the number-was contacted by Danielle on 1 / 2 Jan with a solution but so far it is just promises because I have not been contacted to make arrangements and I am the account holder. I have rep**** twice to the response of Cell C on this platform but it seems like I've been wasting my time..... Cell C, can we please resolve this issue now. I can't keep on paying for a service that can't be used.
