poor communication and service

I have had a very poor and unprofessional experience with Blue security admin and technicians. they phoned me in Feb 2023 telling me their technicians are going around checking batteries because load shedding have caused most faults and they are checking for free. well then they arranged a date for their technician to come and i told them I'm not around but there will be someone at home and I pleaded with them to give me feedback of what is wrong after they have checked before they can do anything.

my sister told me, they came just for less than 5minutes and left without telling her what they did or what was wrong but she assumed they already communicated with me or at least they will as they promised but they did not. I waited for feedback and 3days past still no feedback then on the 6th of march 2023 i received an invoice charging me hourly labor costs for call out and battery replacement , I was so shocked ' poor me i was still waiting for their feedback but they decided to carry on without my permission and did not care enough to inform me, they just decided to bill me.

I queried this with them on the same day 06 march 2023 asking about why am i being charged call out since they are the ones phoned me in the first place saying technicians are checking for free and they will let me know the problem before doing anything but i did not get any feedback only the invoice and the lady called Jodale Krishna came back telling me that after investigation with their supervisors they decided to only charge for the battery and not labour. regardless of unhappy i was with this decision because they claim they have changed a battery without my permission after i have asked them not to do anything before giving me feedback of what is wrong with the battery but i accepted that i will pay for the battery anyway.

I then requested a new invoice with credit note, Jodale Krishna told me she has spoken with accounts department and they will issue me with updated status with credit note, that was on the 10th of march 2023 then i waited but received nothing up to today instead they debited the full amount of R 1550,36 on the 27 march 2023 on my account without any communication or even receiving statement so i assumed they did not carry on with the credit so they just included my monthly fee on that invoice and debited my account without any communication.

i am very disappointed and upset with the way they treating clients, they do not care about inconvenience this has caused because when they debited this amount i did not have enough money on my account as i was not expecting this and i have incurred bank charges and when I phoned again today they telling me credit note only got approved today on the 28th of march, what kind of service is this!

I'm very upset with this poor and unprofessional service starting from their technicians changing batteries at my house without communicating and charging hourly labour call out when they did not even spend 5min and they said technicians were checking for free, and they left without saying a word just because I was not there and didn't care enough to inform me after that. this is unacceptable and i don't even know for sure if they replaced the battery or maybe repaired or maybe something else was wrong, i don't know i just had to deal with their ridiculous invoice and non permitted debit orders. the bad communication is the key here, it seems they only care about taking money before anything else, where is good customer service in all of this?! very disappointing.
