No DLA Payment for 2 months?

I wonder if anyone can give me some advice?
I have been in receipt of DLA higher rate care for the last 15 years and it has enabled me to survive.
Last month my usual payment failed to arrive in my bank so as I am not able to use the telephone, my carer contacted the DLA unit at Blackpool to try and determine the problem. They promised to call back within 4 days. They have not yet called back.
Over the past 4 weeks, I have written 4 letters to the DLA unit but have not yet had a reply to any of them.
This week, I was due another payment of my DLA allowance and again this has not materialized.
I am not sure what to do now.
My mental health and financial positions are deteriorating rapidly and what with my mum being in the hospice with terminal cancer, I have just about had enough.
If any kind person can give me any guidance, I would be very grateful.

Gordon,
thank you so much for your reply.
My carer did have another go at contacting the DLA unit by phone yesterday but after being on hold for 15 minutes, the credit on the phone ran out.
Whenever, we have tried to make contact by phone in the past, we have always been told that someone will have to ring back as they are unable to access a protected file.
Usually, nobody ever rings back.
I have tried contacting my MP before to seek help but they have never been particularly supportive.
What with my mum being in the hospice and my financial position becoming highly challenging, it is looking pretty black.
Thanks,
Jo

I would still try your MP.

Do you have any relatives or friends who could phone using their phones?

Thank you again for your advice, Gordon.
No, sadly I don't have any friends or relatives apart from my mum.
I shall just have to be patient a little longer and see if any of my letters get answered.
I can probably last two or three more weeks before the money runs out, so I shall see if I can hang on till then.
Thanks again,
Jo
