Vodacom bad - quick to sell but slow to deliver

I was sold an "add on product" by vodacom via telecoms. The person said it will not cost me extra, they are restructuring my package seeing that I have been a customer for about 30 years. I asked several times if it will cost me more money and he said no. So, I received a laptop and data card. Well, few weeks later I was charged +- R500 pm extra on my monthly debit order. I lodged a complaint with vodacom via email. All great for Vodacom - they did listen to the recording and confirmed that I was misled by the deal. They promised to collect the laptop and refund the +-R500 pm automatically deducted from my account. We'll, after several emails of follow up from my side, and promises from vodacom that it will be sorted after "24-48 hours".... Well, it's nearly 3 months later, and they still did not collect the laptop, refunded my money and are still deducting the +-R500 extra per month.

They once called my husband for some reason.... to collect the laptop, arrived at our gate on a random day. We were not at home... Never to hear about another collection again! No email, no call, nothing to follow up. I spoke to few vodacom agents, they promise to sort it out.... And I'm still waiting. I mean really, what do I need to do to sort this out???? I pay via debit order....should I just stop my debit order and find another provider after 30 years with vodacom??

Their service is pathetic.
