Telekom is useless

They are useless, you apply then get told you are accepted and will have the first debit go off in 48 hours and then delivered in 7 days call in 13 days later to be told it's insufficient cause my living expenses are wrong how on earth can my personal living expenses be wrong unless they paying my stuff for me without me knowin and at there their own expenses I advise that nobody apply for any contract with them but rather save and go anywhere else to buy it cash Telekom is useless
