Pathetic service experience

Pathetic, being waiting for my contract upgrade parcel since 07/09/2020 and no one bothers to call and update me of the course of delay. I decided to call yesterday only to find out the courier came to a wrong address, but they didn't call to let me know. Well I called Vodacom and I'm told my delivery will be rescheduled for Tuesday 15/09/2020, I demand to speak to a team leader, he is in a meeting and he promised to call me within an hour . I called in three times and every time I called I'm promised an email will be sent to him reminding him to Call me, up to now I haven't received a call, they have incorrect address on their records, they are aware I have not received my parcel, they do not call me, I call them I'm not assisted, I'm very much devastated and wondering if I will ever receive my parcel. I have been doing business with Vodacom for ages, this is utter nonsense, I have never had such an experience. We pay for these services and we deserve better. MTN, hook me up please!
