Pathetic Service from MTN

I upgrade my line on the 2nd of November 2020 through Retentions. The Agent Neo Masilo did my upgrade for me, I upgraded to the Huawei P30 Lite 2020. I was given a 1 month credit on my Line Rental which was approved. I received my handset on the 9th of November and until Today I have still not received my 20gb Promotional Data and now I have received my statement and have Not received my 1 month free line Rental. I called and mailed Neo on Numerous occasions and she has not resolved this issue. I am now Tired of Mtn and there lies as they don't appreciate their Customers and are not willing to assist.
