Cant Trust Cell C's service

Feb 2015 - Took out a new contract for Wi-Fi with a R50 Cap - Call centre spoke to Riaan and to me to confirmed the Cap of only R50.<br> May 2015 - Got a bill of over R1700 for usage - now apparently the cap was never requested.<br> Branch Manager - Shani Smit - said she will follow up and call me back - don't phone back - just send a mail saying this is your responsibility to pay the account - unacceptable and unprofessional.<br> Requested the recordings from call centre - Branch have to request it - spoke to Riaan - he will do so and after one week I had to do a follow up - now Riaan tells me I gave a wrong number and I only saw the Wi-Fi number 1 1/2 month after usage when I got my 1st bill.<br> Internet shops ask R15 / hr for usage - how could I have used R1700's usage and that after the 2G was already used.<br> Couldn't connect the whole month of June to Wi-Fi - went to Cape Gate and contacted cell C call centre - sim card not in modem but the lady tells me that she can see the usage is running actively and we used almost 2G for the month of June already so how can u trust this people after I've been with them for more than 10 years already. Every time you speak to someone its a different story.
