unfair treatment

Dear reader As of today 10 March 2023 I have totally given up on Vodacom as my service provider after over 20 years of being a loyal and diligent patron . Sad to say the least as I have been battling and negotiating since 2021 January-February after receiving advise from them to migrate to a lower grade package as Im not using all the benefits APPARENTLY on the existing one. I agreed on the basis that IF I AM NOT HAPPY CAN I REVERT TO THE ORIGINAL PLAN and the lady on the other end confirmed this ,so i said ok why not pay less for a plan Im not totally making use of, only to find a bill the following month for R1300++ over my usual monthly payment ! The worst part is that after contacting Vodacom and explained to them I do not wish to have a higher bill and was expecting a lesser bill pm ,kindly revert me back to my old plan... I was told it no longer exist!! How cleaver of them to get me paying more ...Nevertheless i sucked up paying the new evolved plan for next 20 so months and then to realise that after being out of contract still charging me for more than the service they provide and incl a handset payment which initially was over 24 month period ? I have been from pillar to post from post to pillar and more for 6 months now only for Vodacom to suspend my service after just making payment due to a arrear amount that they made/created and this after them or the call centre or the upgrades department the legal and or collections department CONFIRMED THAT THERE IS A MISTAKE !! on my account ? WHAT ON GODS GREEN EARTH ARE YOU DOING? you wish to bully me a small Patron who has been paying upwards of R5000.00pm or R7000?pm and after being with you for over 20 years I get this insanity treatment ? SHAME ON YOU VODACOM SHAME ON YOU ! I have been trying to resolve this issue more than past due years, with YOU ignoring the hell out of me or disregarding me and giving me SR Numbers like its going somewhere just for you to further tax and charge me ? ENOUGH! I will take this further as its NOT fair or reasonable and this to me is oppression to say the least also now that Im in the mood and have all statement of accounts I can see that for many years that Vodacom has been overcharging me .... I went out of contract period and was charged in full more than once DISGUSTED AND DISGRUNTLED ....
