MTN- Poor customer experience

Very poor customer experience. From wanting to renew my contract I ended up cancelling and moving to prepaid to now deciding to move to another service provider completely after being a customer for close to 20years. The upgrade experience was poor, went through the process only to find out that the upgrade was cancelled without my knowledge. Upon cancelling I was then advised the last debit would come off on the 1st of December which it did. To my surprise I was then debited again on the 15th of December. After calling in I was then told to wait 7 to 14 days after MTN’s stuff up. As a customer I now have to wait. Further more my other debit orders will now bounce and I will be charged missed debit order fees by my bank which MTN will not compensate me for. As I mentioned to the advisor, i am disappointed that I will now be porting my number to vodacom after so many years with MTN. I really hope that the overall service improves and that customer experience is placed in the forefront of all future improvements. Very disappointed.
