Poor poor customer service

I have been having issues with vodacom for like about a month now. Some two weeks ago, one of my lines was blocked i.e. Put under admin lock for whatever the reason. I called vodacom to find out what was the matter, my calls were dropped a few times. I send a review through hello Peter to get their attention. I was called by some guy from customer service and he promised to get back to me, he didn't. My account was debted again for the monthly premium and the line was still not sorted out. I made endless calls and still no one seems to get what was the problem. I was ready to go to their head office in Midrand because I am not happy with their service at all. Some of the reasons are got from the call centre agents are - there is ***** investigation on your account, you didn't pay your account, there is high consumption of data or airtime used on this account, the account was credited with benefits that are not supposed to given to you... Is just endless and frustrating. None of these information given to me made no sense at all, my account is up to date, i have never missed a payment. I have never received excessive benefits outside of what I am paying for as per my contract. I was left confused by vodacom. Saturday the 3rd December, I went to one of their outlets to see if I can get some help. I explained my situation, the guy took the phone in question and reseted it and corrected the error. He then said they have been receiving similar query they too don't know what's happening or what happened. I'm so disappointed at vodacom for this poor service, is not the first time I have the same experience with them, in fact I never received any good oe great service via call center. Is better to even go to the shops or head office and speak to them live
