Vodacom Debt Collectors calling me for someone else and lying!!

So I received a phone call from a number, the gentleman didn't give his name, however, he requested information from a friend of mine, under the pretense of being from A-Z Couriers and there was a package to be delivered.

I provided the caller with the information requested and hung up the phone as I am working full-time. I tried calling the number and was greeted by someone else, stating they are debt collectors for Vodacom.

I do not have an account with Vodacom, nor am I the person they are looking for so how my number was obtained is cause for concern.

As previously stated I work full time and DO NOT appreciate being called from a third-party service fishing for information that I don't have. This is extremely unprofessional and *********. I have requested that my PERSONAL number be removed from their system and that they do not contact me again. Only time will tell if this has been done. This has left a bitter taste in my mouth and I will refrain from giving praise to the service levels provided by Vodacom.
