Vodacom:Terrible Customer Service and unresolved Account Query

I have a Query/Complaint with regards to my account with Vodacom and I have had a constant struggle with Vodacom trying to resolve this. I am really tired of being sent from one department to another and without my matter being addressed or resolved. It has been almost 3 months since I have had this problem and it is still not resolved.

I so regret making deals with Vodacom over the phone because that is how this whole mess started.

I've had a cellphone contract with Vodacom and I have been due for an upgrade for a while and I didn't take it and I just continued with the monthly airtime of about R160 that Vodacom sends me every month on a top-up Plan.

I called Vodacom in July to enquire about taking (or adding) a mobile router to my contract and the agent that was assisting me insisted that I should rather take a router with my upgrade that I am due for because it would work much better. Little did I know that it would affect the number(or SIM card) that I have been using all these years on my normal cellphone for calls and I would have to now use it on the router. The router was delivered to me by Ram and without a new SIM card. I immediately called Vodacom again to let them know of this confusion and I was advised by Vodacom to reverse the upgrade, which I did, and it was still within the first 14 days. I was told that Ram courier needed to come pick up the device after 10 working days and this was another struggle because they took far longer than that and I was told that the reversal will be done 5 working days after the router has been collected from me and my account will be credited after that, which hasn't happened up to this day.

I noticed after the beginning of September that there was changes on my number(Plan). I could no longer load airtime on my number and I couldn't check my balance as normal. Vodacom changed my plan to open/unlimited calls without me agreeing to this. I immediately made Vodacom aware of these changes they made on my plan or account and I asked them to immediately change it back to the normal plan that I have been using all these years. They were so lazy to look into the matter and they kept on telling me of their useless procedures. No one took this seriously enough and I have been sent from one agent to another, I have called the after-sale Department and Upgrades department countless times (ever since the beginning of July) and no one seemed to be able to help me. It has been a big inconvenience for me. My account/bill now stands at R4000 and I have never spent this rediculous amount on just calls. I have called Vodacom countless times to change or fix this and everytime I contacted Vodacom I was told of these uncessary procedures. I have tried emailing their customer service and my matter is still pending and it keeps moving from one Department to another without any final outcome. My account has not been credited and it is still standing at R4000 plus which I am not going to pay. Had Vodacom attended to this matter on time my account would not be where it is right now. And I ask that Vodacom retrieve all the recorded calls, as they claim they do when we call their customer services for record keeping. I am very unhappy with Vodacom's customer service, their inability to address billing matters on time. It is clear that vodacom just wants to make money unfairly out of us and they are taking our patience and loyalty for granted as customers and their customer service is just super terrible. Please get your act together Vodacom!!!
