Incorrect billing

I had a call from an advertising company for Protea Hotels to renew my membership. I requested payment to be spread, but unfortunately full amount was deducted.I requested the transaction to be cancelled and was told by the manager that they are going to investigate the matter first. I was very disgruntled because I still had to reserve money for my debit orders to run. I received bad record from my bank as some of the debit orders were rejected due to no funds available.<br> <br> I made a follow up call to the accounts department and they said they will follow up the matter with the marketing company and it will take 10 working days for refund to take place.. Later I received an email congratulating me on renewal of membership.<br> <br> I wrote an email to inform them that I am not interested. To date I have not received any response and no refund or indication as to whether I will be refunded or not.
