multichoice not reversing over deduction of debit

i put through a complaint about 2 weeks ago about being over debited in Sept 2019 and was advised that a consultant will contact me with this regards. until now nobody has contacted me. that's what they do, they keep on making promises that they do not fulfil. they do no want to cancel the debit order either. it seems like once they coerce you into their contract, they don't care what happens thereafter. I am sick on making phone calls and getting reference numbers and being promised that it will get resolved. I have lost all faith in this organisation. something so simple to get resolved makes a customer very agitated when not done.......
