Spam messages never end and service is terrible

I am currently in a contract with Cell C. What a mistake...although that is neither here nor there. <br> My complaint is the fact that Cell C bombards me with spam. I have received 3 messages already this month with useless promotions and offers, direct to my cell phone. The fact that I am already signed up with Cell C irritates me more, because they are already taking my money. Why try to keep selling me more more more more more! <br> Nevermind the actual spam marketing sms's - I also have had problems with my contract since day 1. I keep getting billed over R400 on top of what I already pay, and whenever I go into the store to find out why it looks like my bill gets doubled each month nobody can tell me why. Literally, I have been in 4 times to see to this and I STILL have no answer. Im no rocket scientist, but neither am I stupid. So really makes me wonder what Cell C is actually doing! <br> Bottom line is - wouldn't recommend going on contract with Cell C.
