Awful call centre

The enrollment was inpressive but then I got the first external payment into my account and they immediately blocked my account with a number that I must call. Waiter many minutes to the most awful noise that they call music only to be told I must send an email with proof of payment and then call again (and obviously go through the same excruciating waiting again).

I can understand the need for a first time proof of payment, but: 1) why not tell me about teh need for proof of payment before hand? 2) why not give the email info in the blocked and avoid theit awful call centre? 3) why the need to call again? 4) why such truly awful 'music'? Congratulations - you tuned a very posiutive client into somebody that really dislke you. Truly awful!
