Mobile contract double charging (since December)

[KrisztianNagy]

Hello Vodafone Team,

In the past 5 months your company is charging me double fees than the fee which is stated in my contract. My original rate is 57,99 Euros (Vodafone Young 2017 M mit Premium Smartphone Special), although I am getting charged with an additional 57,99 Euros each month. I already complained in the shop where I made the contract. I have contacted every single employee there to solve this problem and in the beginning of February they told me they already deleted the other contract but I am still getting double charged and nothing has been transferred back. 

Due to this pandemic situation I tried to contact them via telephone in the past few days, nobody answered although I called the given numbers several times.

How can we solve this situation? Which kind of documents do you require from me to fix this? 

Kind regards,

Krisztian Nagy

Hi Krisztian,

have you both tariffs on one bill?

Could you please show us a pic of your last bill (anonymized)?

Hi Krisztian,

on your invoice you will be charged for 2 contracts that you have concluded. Please contact the shop where you have concluded the contracts. Only there can this be clarified.

Kind regards

Bernd
