14700 spam text messages & poor signal.

Almost every day, 14700 texts me about a real deal promotion. <br> <br> I am not subscribed and they give no option of stopping these sms's. <br> I am really irritated and frustrated and want nothing to do with this promotion. In the last two months, I've recieved near 30 sms's. <br> My signal is also dreadful. MY phone disconnects at random, sometimes even during a call.<br> <br> I am due for an upgrade but I am strongly considering not staying with cell c as they have only shown poor customer service and offer overpriced deals. <br> <br> Please stop.
