Lack of assistance

Logged a query about more than a week ago, still waiting for a 48/72 hours turn around time. Multicoiche failed to debit our account on a price lock contract some time last year. We called them to notify them, they said it’s a common error with price lock customers and we made arrangements to settle. A few months down the line the problem occurred again and another arrangement was made, about 3 to 4 arrangements were made but the problem kept on reoccurring, they just couldn’t be consistent with the debit orders. Price lock contract has expired and we are now sitting with a R2000 plus bill which was caused by their failure to debit our account. We were told to go to the nearest walk in centre to get assistance but non was provided. We are now being sent from pillar to post trying to sort this out , everybody at Multichoice is “escalating” the query and the “relevant department is going to contact us”. We have exhausted all avenues now and we are not getting anywhere.
