Poor service from mtn

Mtn is the worst experience ever. I went to them on 28/11/2023 to apply for a new contract. I gave them all the requested documents and I was told to wait for approval. Last night I received an sms that my vetting was placed on hold due to other documentation the require. I was told to go the store to enquire about what additional documents were needed. This morning I went to the store only to be informed that the lady who assisted me is day off, therefore they cannot help me until she comes back. So now I must go back there again tomorrow only to ask what additional documents are needed, then I must go there again to sign documents should my application be approved. I stay far from the store. I even phoned 135 and *** for help. They told me they couldn't help me. I must go to the store. Why is it so difficult for a customer to apply for a simple contract? Why did no one at the store not inform me of an incomplete application? I gave all the documents the agent asked me for. This is really unacceptable.
