Vodafone is quite a pest in terms of spam, leaving them led to two dozen emails, a bunch of SMS and five phone calls. It is not surprising they don't bother to check spelling on their spam anymore.

Especially the emails, resending me literally the same offer of a 5€ rebate per month five times is just offensive spam. The other ones were just variations of the same offer with different styling.

T mobile is worse. They send me sms adverts based on the location of my sim card. Even a flip phone doesn't help

I got tired of Vodafone's spam and switched to another operator altogether. Vodafone cheapest plan was 6€+VAT and I got the most expensive plan form the other operator at 5€ VAT included which included more benefits. Plus the added bonus of no spam. They just kindly remind you to pay your bill three days before it's due.
