Worse Service Ever!!!

If I could give 0 stars, I would! Our bank account changed, & I submitted the new debit order details on the Vox app as I was told. We received an e-mail requesting proof of banking details, which we sent immediately. Since then, we had to submit our proof of banking details 3 more times and it has now been 3 months later & our debit order details has still not been changed! On the 2nd of February, I received a mail stating that our services will be suspended if payment is not received in 5 days, to which I immediately rep**** with proof of payment (payment was made on the 31st of January already). This morning our services was suspended due to non-payment! I have never, in my life, received worse service from anyone!
