GETBUCKS GIVING CONSUMERS BAD SERVICE

I recently received an sms from Getbucks basically saying that they are going to attempt to deduct my installment on the 17th of December and there is nothing that I can do about it...?! I phoned them with the intention of instructing them not to proceed with the debit order on the 17th of December but on my normal deduction date of the 1st of January 2020. They said they cannot do that as everything is already loaded onto their system! Now, Cell C sends you exactly the same sms, BUT, gives you an option to reply YES or NO. Now that is customer service by providing the consumer to actually choose what they want to do and not forcing them to pay when you don't want to! I am on holiday on the 17th of December and have not budgeted for Getbucks to ***** my money on the 17th! They have given me an option to provide them with my bank statement after the amount has been deducted to prove that the money remaining in my account is not my salary, but hello, I am on holiday, I don't have access to e-mails etc.! Now I have to go through all that trouble just because Getbucks decided that they can do just what they want! PATHETIC!
