TIRED OF NOT HAVING SIGNAL.

I am absolutely sick of Cell C. I have been been with Cell C for almost 10 years and this past year has been absolutely horrible. I pay almost R2000,00 a month for a contract (signal) which barely even works, I rely on my phone for work and have missed multiple calls from clients due to there never ever being signal. I have done everything Cell C has told me to do yet nothing is working. I always get the same excuse that it is because they are migrating to VODACOM. It always seems to be the customers fault or phone when the signal is not working. I can not get out of my contract unless I pay a massive amount. So when it is time for me to upgrade again, I will be migrating to another service supplier without thinking twice about it. Cell C is absolutely useless and has gone down the toilets extremely quickly.
