Bad service

I just recently paid my vodacom account , which was suspended due to that Vodacom decided to deactivate the debit order , now my account is up to date , I have spoken to Elvis and he told me that they only did a pro rata on my account , I don’t understand why would Vodacom punish me for their fault and decided to not give me my airtime and data for the last 5 months .I am really not happy on how I have been treated by Vodacom considering I have been a very and extremely loyal customer to them. I am requesting fir all the airtime and data fir the 5 past months to be re instated on all my SIM cards
