Poor customer service

On the 20th of April I app**** on for a SmartBroadband Wireless 20 GB with a Huawei B315 LTE Router it was successful and I was debited on the 23rd of April and still no feedback on when I am going to receive my device. I tried calling the contact centre but no answer this morning I was holding for 52 min since 8 o'clock in the morning this is ridiculous and very poor customer service
