Incredible Connection Online Order

I ordered an Air-fryer over 4 weeks ago and I have not once had any contact from incredible connection to inform me what is causing the delay and when i can expect to receive my delivery. The item was shown as 'in-stock' and available for delivery when i placed the order as it was seen as an essential item during the lowdown period. I had many calls to the call center that were never resolved and when promised someone would call me back regarding the matter, i never once got a call. Today I wasn't able to track my order so once again i called the call center to find out what was going on, I was informed my order had been cancelled because there is a back log with the supplier and instead of customers complaining about the delay a decision was taken to just reimburse the customers(without communicating this decision)...so now i have waited over 4 nearly 5 weeks for an order that will not be arriving and have not once had any communication from incredible connection to let me know what is going on. I understand there are back logs but update your systems and inform us about it. really poor service and communication. will not be buying from the online store again.
