Bill incorrectly again

[#1]

Right let's try this again, https://community.plus.net/t5/My-Account-Billing/Massive-bill-overcharge-after-being-told-exsisting-... is when I was charged a large amount due to Plusnet billing me incorrectly months prior and then deciding to charge me the 'missing months' I hadn't paid while you fixed the issue.

Guess what despite acknowledging the fault and refunding me the amount you overcharged, as well as being confirmed what I should be paying (found in question 190606668), whatever 'fix' applied to my account hasn't worked and I have just been handed a bill for the wrong amount, again. I wouldn't be this mad if I hadn't gone through all the stress of trying to make sure I had money available to pay for the 'lump sum' last time, I don't really want to go through it again in another 3/4 months time 

Not once have I been charged correctly since I requested my package changed back in November last year and I know you stop the incorrect bill from being charged, just please put whatever band-aid you can on my account, I don't want to be here next month or the months after waiting for my account to finally be correct

Thanks for reaching out.

I'm sorry to see your latest bill is incorrect again. Unfortunately this is because your contract is showing as pending in the billing engine, which means that any discounts we're adding aren't sticking to your account.

I've added a credit onto your account to cover the missing discount this month and I've also arranged for us to manually apply a credit before any generated invoice until the problem with the automated discounts is resolved.

I've also added a reply to your support ticket 190606668 with more information.

Hope this helps.

I thank you for the prompt response, considering you have to manually fix the issue at your end I will keep an eye on my bills and I will get in contact with you if anything goes wrong - I have also added the exact contract agreed upon to the support ticket to make sure the correct discounts are applied to make fully sure I will be billed correctly next time
