Wrongful Change of Migration/Contract

I was sent an SMS today stating that I have breached the fair use policy whilst I DID NOT. Then M&Y changed my service arrangement from the original to a MINI Me package which is not what I signed for.

I had used less than 150 calls (150 is maximum to breach the fair use policy) and I am on a monthly purchase bundle of 100 megs. Since I have signed up this deal, some 20 months ago, I have had a recurring 100 meg bundle. I was told that if I had the bundle it was not necessary to use the 50meg because I am paying for 100 meg. And so it has been like that for 20 months. whether I used it or not it has never been questioned because: a. I am paying for the 100 meg which gets nullified at the end of each month whether I use it or not. b. The fact is I am buying the 100 megs which is within the fair usage policy rules c. Since inception this has been acceptable and now they decide differently. d. Why have me be buy a bundle recurringly where unused data is never carried over and still penalise me for not using what I purchased. e. The fact is that I have purchased the 100 megs without possibility of refund or carry over. f, The Fair usage rules have not changed since inception of my service from M&You mobile -- had M&Y specifically changed the policy wording, making it different from inception then it would be acceptable and reasonable to claim i have breached the policy. g. There have many a time where I have not used the minimal 50megs data and tehre was no reason for breach nor was tehre any notification of change of rules - so how is it now that this is so.

* see attached copy of part of email sent from M&Y where they ask that I buy a recurring data bundle to prevent breach of fair policy usage -- the very same reason I already had a recurring bundle of not 50 meg but 100 meg - double what they ask.

I have never had this problem before. I also called in a week ago when M&Y sent me an SMS saying I need to use 50 meg data and their customer service staff checked and confirmed it was an error from your side. I am sure M&Y have call recordings to verify my call on 22nd November 2017. The call history on my account will also show that I called after the sms was received.

M&Y have also changed my login facility where I cannot retrieve any of my history or invoices for the last many months where it can be verified that not much data was used but I am charged for a full bundle anyway.

This is a breach of contract by M&Y and therefore I ask that M&Y reinstate the original arrangement.

I have called them more than 10 times today to no avail only to have a service lady answer at 5;27pm who claimed to be a senior consultant to have a seriously bad attitude and cut the call off. She rudely asked that I wait till Monday when they have the time to deal with the issue. Again there must be a call recording by M&Y about this too. everytime I called today, the automation placed me on hold for 8 minutes and then someone would take the call and immediately cut it off. this happened on each attempt except for the last one. This is a company that shows absolutely no regard for its paying clientele. It is disappointing to say the least.

I just want M&Y to re-instate the original arrangement immediately. Thank you
