MTN making me ANGRY

I'm so tired off this, e-mailing every day, the phones can't phone out or there is no signal on them. I rica-ed all sim cards paid my accound up to date, I even have credit, looks like I need to change to another provider, MTN is just not giving me good service anymore. Even old contract phones that are paid up like my Samsung Tablet has no signal.

This number ********** 103 has no signal, it worked fine on Monday and my Tablet worked fine Yesterday.

E-mail from MTN, Still no signal on phones.
