Bad customer service

I would like to share my bad experience with Vodacom. In April the Sales department called me selling the 10G data and told me that I’ll be able to cancel the 5G that I am currently using, after receiving the package I then called Vodacom to active the 10G data and cancel the 5G data. The guy from the cancellations department told me that I will be charged cancellation fee If I cancel the package since the 10G was not the upgrade but a new contract, meaning I was sold lies. I was very angry and decided to cancel the 10G data contract, logged a request with Vodacom and Ram couriers to come collect the device. I don’t know how many times I had to call and remind Vodacom and Ram to collect the device. Ram eventually came to collect the device, I called Vodacom to cancel the services. What irritates me is that they debited me for a device I am not using, I reversed the debit order and called them to clear the arrears, instead of fixing my account they decided to block my service. I called the collections department yesterday and spoke to Abongile she made me a fool, she kept me on hold and transferred my call to the customer care department without informing me. This is the most horrible customer experience I’ve received at Vodacom, I do not what are they doing with CSAT score and AHT\Hold time stats, it looks like they are measuring to just keep with the industry standards. My monthly debit order of R489.32 was successful, I only reversed the debit order of R184.09. I want my account to be cleared, my method of payment be converted back to debit order and my services be unblocked.
