Bad customer service

I do not know if Vodacom really doesn't value their customers, it is 3 months later and still have had no response from them or maybe I should take my complaint to the Ombud for stress and inconvenience as I am not taken seriously as the customer, none of their staff members have customer service, I got an sms on 24 September that my tablet has been fixed that was taken in June then I went to the store to check if it has been delivered then they said they will call me the minute it gets to the store still nothing job number:***8 and now the sim is lost because of your inconvenience which I am not even willing to pay for. I need someone to call me and resolve this complaint as I am tired of waiting for your pathetic service.
