Vodacom lies to customers

My husband had taken out an online contact with vodacom in May 2022.The deal included the phone once off 120g data and hauwei ear buds we dealt with a lady by the name of Rookaya i repeadlty asked her about the deal and the ear buds and always answered yes the deal includes the ear buds .When we received the package we did not receive the ear buds we contacted the consultant Rookaya she said she will do a follow up and get back to us which she did not we had to phone and do a follow up and still got no answer i had phoned and explained the situation to another consultant which then she advised me to send the screen shot of the deal to a manager named lisa which i did no response was given back from lisa i had to contact them and ask to speak to lisa ....lisa explanation was that Vodacom made a mistake and they have the right to and theres nothing they can do she can give me email addresses to take it futher .....wen my husband spoke to rookaya he said if url cant sort the problem out i will have no choice but to return and cancle the deal she said she dont think they can do that she will have to check with management so she asked my husband do u want to return the phone after the conversion and my husband repeated to her if u guys can sort the matter why should i return it ....without consulting or even getting back to us they sent the courier to collect the phone so vodacom rather loose a customer than find a solution to they mistake . at the end i got no were and they prefare to take the phone back and tell me they have the right to make mistakes
