Chasing customers away.

Let me start at the beginning, beginning February I was called numerous times with regards to upgrading my number as to the account was eligible. I declined the requests time after time as to I want to wait until the package expires then upgrade. March, I got a sms that my account is outstanding and that I need to be paid within a set time, I found this strange as to for the last 20 years with MTN it went off via debit order. I called the 135 number and was told that someone moved my account to a cash account, and I need to visit a store to rectify this. End April I went to the Ermelo branch with requested my banking details and verification documents. Until now nothing has been rectified, instead my accounts were moved to the MTN Business department, and all my packages changed costing me more than before. None of my linked cards are working, nor is my package correct. I demand all my accounts moved back to the personal side as well all my services restored and packages reverted to what they were, then let’s upgrade. I have not given permission to move or change anything except my baking details. I also request that any additional cost incurred by this be refunded and the guilty one to be disciplined. Three months to do a simple thing and sit with this is not good for customer services not business as such. I’ve been a loyal client for 20 years and never missed a payment, I feel this case needs special attention. If it comes to it, invoice me for 24 months and ill gladly pay you, hence everything is the way they were. If it is not possible, please inform me and I will seek help from another services provider.
