Complete Lack of Support Process and Empty Promises

I have been requesting a vat invoice for an online purchase for a month now

I started the first 2 weeks via email and never got any reponses

I moved over to whatsapp. I spent roughly 40 minutes each day asking for this invoice. Every single day more fustrating than the last as i was promised everyday that i would have it sent to me. Every single day i had no resolution, no feedback. Every morning i start over again with a new person and the cycle repaeats 5 days in a row this week. and multipe requests in past 3 weeks. All i get is the "" We are sorry to hear this" and then the "we have escalated your issue" and everyday nothing.

I am appauled at how bad support is. I am practially begging each day. This is such a simple request. How can it take multiple weeks. and how can you lie to a customer 5 days. Dont tell me you will call me everyday and then you don't call me. And dont tell me everyday you have escalated it and then shun me off and nothing happens.

I have been asking for sombody to call me and explain whats the issue. I have asked so kindly for somebody to send me an email so i have a point of reference to follow up.

Seriously? i just cant understand it. I am so exhsuted from getting upset about this daily and made a fool.
