terrible service

Cell C fibre is currently providing me with the worst service I have ever received from an internet provider. They have no clue what they are doing. My internet went off on Monday. I have phone numerous times and logged four different incidents with four different consultants and not on one of these claims has anyone gotten back to me! When I phone I am told someone will get back to me within 24-48 hours. It is now past 48 hours (96 to be exact) and still I have received no response. When asked how it is that they will get back to me within 24-48 hours i.e. will someone phone me or will they come to my house to fix the internet, the consultant just kept saying:...they will get back to you within 24-48 hours... Shocking
