Disgusting Service

The Online and customer service is Pathetic, i placed an order on the 19 May 2020 only to receive my parcel in drips and drabs, eventually i received my last parcel only to come find one of my items is not in the bag so i called the customer serivce online and they tell me it was delivery after informing them that the last parcel was delivered but 1 item is short they tell me they will investigate and get back to me in a day or 2. ok i wait no update no call or email to say Miss Foster we are still looking into the matter nothing after 14 days and still no call no update and no email, I the customer has to be the one calling and following up on them holding on the lines for sometimes like 20mins only to be told they will log a call, every single time i call wanting to speak to the agent i have been dealing with then the agent is off or not at her desk then i request for a manager then the manager is either gone to the toilet or out and then i asked for the manager to contact me no call from the manager. I understand that people are not at work and we busy with back loads but there is nothing wrong to acknowledge the customer, i rather have a refund to my account and go buy the product somewhere else. I need a call by the end of today from a manager to help me or else i will take this to the Ombudsman cause Facebook they seem to ignore my posts . My details are ***
