Terrible MWEB service.

We have just joined Mweb end of November and a week later our internet woul not work.It was off for 17 days and only after numerous calls and wasted money on my part did i finally get someone to help just to say that our sim card was faulty.They sent us a new sim card and then charges us R199 for delivery for a fault that was THEIRS.Now they say our account is arrears because of the R199 and they just switched the internet off. Have had nothing but terrible terrible service on their behalf.They need to credit us for that 17 days we lost and they should cover the delivery fee because it was their product that was faulty.Shame on you MWEB!!!
