Terrible service from Vodacom I

I have a complaint against vodacom that I've been trying to resolve for almost a year now still not resolved. What happened was in last year an agent from vodacom phoned me and told me that I qualify for a free gift from vodacom because of being with them for more than 10 years at end of February last year they delivered this so called free gift at my house. In March during the lockdown period the raised my debit order with more than 600 rand when I called in trying to find out what was going on I heard that I'm paying now for this so called free gift. I asked them to come and fetch their free gift as I don't want it after an endless struggle they collected the stuff in March and was suppose to credit the amount on my account. I was so upset with the hole issue and stopped the debit order with them they confirmed on a sms that the debit order has been stopped permanently. From April last year I've been paying my account manually. After confirming that they have stopped the debit order and receiving my manual payments they still submitted the debit order as well. Then it bounces because I pay it manually and then they charge me a penalty fee of 108.00 that has been going on for months. Every week of every year since last year February I've been on the line to vodacom trying to resolve the matter. Then eventually they reversed some of the money that's putting the account in arrears. Yesterday and today my lines are suspended because of their mistakes that they can't fix yesterday and today I paid all the outstanding monies on the account just to get my lines up and running because two businesses are down now and can't operate due to not having phones or internet access. I've made the payment this morning at 8 its pass one and everything is still down. I'm beyond repair at this stage I've wanted to cancel all my contacts with vodacom for breach of contract and go to another provider but apparently they will not cancel the contracts until the expiry date. I've never received such terrible service from a Company like Vodacom. Being a customer for so many years and not skipping one payment in all these years this is certainly not a way to treat a customer.
