TERRIBLE AND SHOCKING CUSTOMER SERVICE!!!!!

I took over a Neotel contract through a friend to assist in using the phone for business purposes. I am not able to firstly get signal (CANNOT RECEIVE and PHONE OUT) from any area in and around Johannesburg. I have asked for the number to be changed and it has not been. I have called the call centre 3 times without results. I have emailed as well! I have asked to speak to a senior consultant to sort this issue ASAP and I am still waiting (2 weeks)!! I called again today and following my lengthy introduction a lady pretends she cant hear me and just holds the line (Her name was Talent). I am shocked and dishearted by the level of service that Neotel has given me. I not only do not have my own signature on ANY documentation however when payment is needed no questions are asked in deducting the monthly R408.00 off of my account. This service is disgusting as I am not only UNABLE to receive/call out or use my internet service but this also affects my business as I am not able to communicate with my employees and customers correctly. I WOULD NEVER RECOMMEND ANYONE TO TAKE OUT ANY CONTRACT THROUGH NEOTEL!
