Bad Attitude and Irresponsible

I called Cell C today and spoke to a useless agent by the name of Nonhlanhla. I have been billed for the contract that expired in June and the amount on my other contract has all of a sudden increased for June and July billing, all I wanted to know was why am I been billed a higher amount when nothing has changed on my contract and why am I being billed for a contract that expired. She transferred my call to customer survey without assisting me this is after I was on hold for more than 30 minutes calling from my cell phone. I find this kind of service pathetic!!! Cell C, please hire capable agents who can assist us otherwise stop recruiting customers cause clearly you don't have the resources to service us! I cannot wait for my contracts to expire,I'm definitely not renewing/upgrading.
