*****ing my money 2 months in a row now

I took out a vodacom contract with them for a tablet with 1GB per month. I stipulated that I will only pay the R89 as advertised per month which they agreed to. I have had debit orders now for 2 months in a row for HOTSPOTTER,RESCUEBOX AND SAFETY from them without my authorisation. Bad bad eexperience and I will not recommend them to anybody. (Still waiting for response after my report last month)
