Current contract terminated by O2 with no reason and a new contract being rejected with no reason

Hi,

I'ma longtime O2 customer having completed multiple contract tenures in parallel for multiple tariffs with O2.

In the last few days I have faced a couple of very strange issues with O2, which have led me to consider taking my business elsewhere, but I would like to clarify things before I do so.

My current contract for HomeSpot was terminated without any reason by O2 with one month 's notice (I had already completed the contract, so it was running with a one month 's notice period ).

Could you please share what is the reason for this termination (the termination letter doesn't mention any reason ) ?

On a somewhat related note, my mobile contract had  completed too and so I extended it successfully a few days back, but when I applied for a new/second mobile contract I was rejected without any reason.

Could you please share what is the reason for this rejection  (especially considering that I 'm still being up sold the new HomeSpot tariffs in my O2 account , so somehow O2 still wants me to buy contracts but strangely not the ones that I want to buy )?

So now I have an existing contract on notice, another existing contract which was successfully extended and a new contract which was rejected.

There have been no major changes in my circumstances lately, so the above events are very surprising for me.

I appreciate any help in this regard.

Thanks!
