Good Day

On 10 August 2015, I app**** for 2 additional contracts with MTN and the service I received was very unprofessional. When I received the two new contracts, I was given the simcards in a loose plastic bag so I did not have the PUK number or any reference number. When I phoned, the MTN 808, the consultant explained that they could not trace the two new contracts that I had recently opened. It was so hard for me to get assistance because I did not have any reference numbers for my two new contracts. When I phoned the MTN branch, no one could help me because the sales lady who had assisted me was not in the office. I was once again left in limbo and unable to use the two new simcards! The whole situation became so difficult that I decided to cancel the two new contracts because no one was assisting me. I phoned customer care and spoke to Abiedah to cancel the two new contracts. After requesting for cancellation, I was shocked this week when I received an invoice for the two new contracts that I never used! I do not want to pay for something that was handled in such an unprofessional manner, in fact I requested for cancellation and the cancellation was not done properly. If the cancellation does not happen, then I will end up cancelling all my existing contracts with MTN and I will happily migrate to another cellullar service provider. Waiting for your response.
