Service delivery

I am a vodacom customer fiber as well as contract . I upgraded my vodacom cellphone contract in February 2021. At the time the were 2 months left of the contract. Which was supposed to end in April 2021. Due to the upgrade terms and conditions was adjusted towards the new contract. However I still had to pay for the old handset. Which I agreed to for 2 additional months concurrently with the new contract. Fast forward to May 2022. I short paid my bill and therefor my services were terminated. After paying the arrears I called the customer service department to reinstate my account. As I work from home I lost 3 days of work due to my internet which services was also affected by that. Revisiting my statements I noticed that the handset which I was supposed to be paid up by April 2021 was still billed for. I I called the customer service agent and asked her to look into my account from the period I upgraded. We both agreed that Vodacom made a mistake by not terminated the payment/billing of the old handset by April 2021. I was promised that they will cancel the billing of the old handset and the amount I overpaid will be credited to my account by this month. Looking at my current bill I saw that I was credited only for 1 month in stead of at least 13/15 months and the 1 month they credit was again billed on the current statement. I called again and query why the promised which was made to me 2 months ago was not fulfilled!!! The agent (Kaya) was his name told me Vodacom don’t cancel any contract automatically. I must call them after the 24/36 months for them to terminate the contract. Which was odd for me. According to me I did that when I upgraded to the new contract. He never addressed the issue of the overpayment and billing of old handset. I was promised that the matter has been escalated to a supervisor (Bongani) who was in a meeting at the time and will call me back today 08/08/2022 before 15:00. As I am writing this now at 17:25 I am still waiting for that call. For all the Vodacom customers who upgraded to new contracts please check your statements because Vodacom is busy *****ing from you.
