A COMPANY MY DAD HAS NOT RECEIVED ANY DOCUMENT FROM YET THERE IS A DEDUCTION GOING OFF HIS BANK ACCOUTN EACH MONTH

My dad has cover with tracker for plus minus R300 a month. He received a phone call offering some add-ons which he didn't fully understand and did not want. The telesales agent was very quick on the phone and then rang off. This was plus minus 14 months ago. He was not happy with this matter but being very busy at work wasn't able to deal with it. He didn't realize what was involved and found that there was a deduction on his bank account of R160 a month. Having phoned the bank a month ago to establish what this "Beam" deduction is, he was given a phone number of a Mr Martinus whom he phoned and never ever got a reply. He then asked the bank to reverse the payment and they never did so. Yesterday having seen the deduction he phoned the bank and was given Tony Walton at TeleMatics phone number - having phoned twice yesterday on ***, no-one bothered to answer the phone - today my dad told the bank to reverse the payment and he phoned at least on ten occasions and asked the operator on two occasions for Tony Walton and was not put through. After waiting he was cut off and eventually left a message for one of them to phone him at the client services and no-one has bothered. He doesn't want to deal with such an irresponsible company where they don't answer the phone or on the two occasions that they did, he was just cut off. He never signed anything and has never received a document from them and he didn't know what they were until today when he phoned them. He doesn't want anything to do with them and wants the deductions cancelled with immediate effect - please will they call him on ***.
