Vodacom - No service

I had the worst experience with Vodacom ever! They contacted me and said I qualified for a contract phone. I exepted the contract which was a R99 per month. The person that explained the contract to me said I will receive a J5 phone. When the package was delivered if was a motorolla 4G phone. I struggled to set up the phone everytime I had to phone another number to help me set up the phone. Long story short. I contacted the call centre and cancelled the contract (2 days later- within my 21 day to cancel). The next morning there was a debit order of R207 that went off my bank account for Vodacom, the arrangement was the first payment will go off my account on the 7th of April 2018. The delivery company came and collect the phone. The 15th of May there was another 5 debit orders going through my account, (somusic, something rescue etc) I contacted the call centre again the next monday saying that I have cancelled the contract why did they take money? And why was the amount R207 and not R99? And also told them about the other debit orders that went through my account. They assured me the money will be paid back into my account. I am still waiting???? This morning 30/3/2018 another debit order went through my account for Vodacom for R207.
