Come on, Cell C. Why should I pay for your inefficiency!

No reception using my wifi for at least a week now. I am now using out of bundle rates. I have contacted Cell C and each time I am told that my problem will be escalated and someone from technical will contact me within 24 - 48 hours. This is ludicrous... I have to pay because of someone else's inefficiency. I have 5 contacts with Cell C in my personal capacity!!! Come on Cell C ... either this gets sorted or I take legal action due to breach of contract.
