Disgusting Service Provider

Hi, I just got off the call with your technical department regarding the 'No Service' cellphone reception on my phone. The first consultant I spoke to before being transferred to the Technical Department advised me that my sim card is active and there is nothing wrong with it. The consultant at the Technical Department advised me that my sim card is damaged which she was unable to explain why. I was advised to purchase a new sim card then call again to have it activated where I will be charged for it. It is really a disgrace that one would be at a disadvantage regarding the service provider without being a fault and thereafter being charged for it. Unless you are able to prove that the sim card is truly damaged I will not be inconvenienced monetarily and therefore will not pay for services I am no longer able to use.
