Not a happy customer

I could not deposit my parcel on time due the locker being offline and struggled for hours to get an agent to properly assist me. The service when trying to escalate a matter via the WhatsApp line is absolutely terrible and I have still not been able to speak to someone telephonically regarding my issue. If this is how you treat your customers then I will not use Pudo again and would definitely not recommend anyone to use it. Please advise how I can get in contact with someone to escalate my issue.
