Unprofessional Service Received.

I would like to lodge a complaint with regards to the service i received from one of your call centre agents on saturday the 07 July 2018, i made payments on my contracts on the 03 July 2018 and 04 July 2018 and on the 07 July 2018 i got messages on both my phones that my phones have been locked and my account has been handed over due to no payments received. i have proof that my accounts have been paid, and when i called the call centre the agent that helped me says that there was no payments reflecting on the system. i requested to speak to the manager on duty which i was told that shes on lunch and that she cannot go and call her cause its her lunch time, i then insisted that she go and call her manager. i waited for about 15 minutes before the manager even took my call. once she took the call she stated that she can see the payments reflecting on her side and that she was going to send an email through to the accounts department. the manager i spoke to her name is Jabu, Jabu promised me on saturday that she would send the email and give me a call on monday the 09 July 2018 with feedback, i have been waiting the whole day today and still no call from Jabu. i recalled the call centre tonight and spoke to Nobuhle, she sent through the email to accounts and said that the phones should be unlocked in about 5 hours time. i would like to compliment her on the great service she delivered. kindly sort out this issue and send me feedback with the outcome...
