Poor Customer Service

On Saturday 18 November 2017 I called the Cell C at Mall @ Africa inquiring about stock of and IPhone7 Rose Gold. The consultant responded very promptly and assured me that there was stock of the phone. I inquired from the consultant as to what documents I would require for opening a contract so he explained to me the procedure. Further I explained to him that I have an existing contract with Cell C so he advised me to send a copy of my identity document and proof of address via email to him so they could send it through to the credit department to do the necessary checks in order to approve my new contract for the cellphone required. After sending through all the documents required I received an email from the consultant stating that my contract has been approved and I should come with my identity document and collect the phone at the store as all the paperwork and credit checks have been completed. I managed to get to the store that afternoon so the consultant advises me that they still need to contact the credit department and they would like to speak to the me because things have not been finalised. Fair enough he called through to them the lady on the other side of the phone refuses to approve anything because she states they cannot get into contact with me on one of my very old contact numbers. I explained to them it was a very old number that got ****** a while ago and I gave them a new number where they can call me. The lady refused to listen or call me on the alternate numbers provided and therefore did not approve my contract. I left the store that day and was highly dissatisfied with such pathetic service received from Cell C. She then calls me 30min later asking me questions and then I received confirmation that they approved it but by then I had left the store and the Mall already. The service received was very poor and not upto customer satisfaction. I will never consider taking out a Cell C contract again.
