BAD SERVICE

This is the second time within 3 months that I get billed for out of bundle data usage. I received my message that my bundle will be depleted on Tuesday to state that I only have 50MB left. I immediately bought a new bundle for 250MB and received the sms that the bundle is activated. SURPRISE SURPRISE!!! My account is up with almost R200 and when I phoned to enquire about this, I was told that I used out of data bundle rates. The more I try to explain to the lady that I immediately bought a new bundle, the more she apologized. Her excuse was that sms was delayed. I am sorry, I am fed up with bad service. I have 5 contracts with Vodacom and I get treated like this?? Is it convenience that we receive sms late? I have the Vodacom App on my cell phone and check my balances all the time. This is not acceptable for me to pay for bad communication and service. I am then told to put a block on my phone?? What??? I am not a child that has to be controlled like that. If your service is up to date, this kind of thing will not happen.
