Poor Service at Mtn South Africa

Due to lock down and covid19 regulations, i was without employment since level 5 till level 2 and my Mtn account also fell in arrears, i have started work and needed to settle my account, i called Mtn last week of December and was provided with Ref:*** and was advised to call back on Tuesday the 5th Jan to get outstanding amount. on Tuesday when i called, "What a phone tour i went though" i called Mtn at 08h15 and spoke to Ntombifuthi i gave her my acc and id then she said my account is still on old system she then gonna transfer me to a person who have access to new system i hold for a while then got to Ayanda also gave her same details i gave to Ntombifuthi she then told me, she can't access my details coz she is working on new system and my account is still on old system can she transfer me to someone who have access to old system? i had no option but to say yes, was transferred to Mathabo who couldn't help me either she also said they only option is for her to transfer me to someone who can help me at that time it was almost 09h31 still no joy no help. I had to hang up/drop the call as i had other commitment to attend to. What a horrible service, after spending over an hour on the phone still no help.
