Bad service and failure to honor contract obligations

It is very alarming that vodacom is now *********. I have been with vodacom for the past 20yrs but the treatment I received for the past week is shocking. The lack of interest in resolving the query is shocking. Last weekend on Saturday morning I spoke to one of the sales consultants by the name of Pearly. She offered me a phone on special, Huawei 9a nova blue in color the package of R299 for 24 months. She also offered me data including router a parkage of R299 per month. The package is inclusive of 80gs for a day and night which is also on special. She read all the terms and conditions and finalize the deal. To my surprise when I now follow up on the phone vodacom now tells me they can only see the data deal on the system which according to them it was delivered to me which was never delivered. I requested to speak to a manager n on Wednesday 11/05/22 I was referred to Mlungisi Khumalo the case manager, he promised that he will call me before 24hrs. N promised that on the 12th of May I will receive a call from him. Which he never kept the promise. I then followed up with him today he promised that he will call me today before close of business as he escalated the issue. He assured me that the matter will be resolved by today. He again failed to honor his promises. He lacks customers survive and has no sense of urgency. I will like vodacom to listen to the calls and make the calls available to me. Vodacom as a brand can not offer me a deal thereafter fails to honor the contract. We agree on the contract and am expecting them to honor the contract obligation. I want this matter to be send to someone who is deemed to be competent as Mlungisi is *********** n lack knowledge of being a manager. After 20yrs of being a reliable client never even missed on instalments is depressing to receive such a poor service n lack of honesty.
