wrong product delivered / poor customer service

I have been a customer of HC for many years purchasing many products over the years. Every time i ordered something i never received the free gift advertised so in always had to make many calls and arrangements for the items to be delivered. that took time and at a further financial setback! none the less i kept being faithful and on the 23/01/2018 i ordered a king size extra length mattress and bed set. I received a call on the 02/02/2018 to arrange delivery for the 03/08 . i informed the guy that i would only be available in the afternoon as i was attending a memorial in the morning. they assured me they only needed 30 minutes to deliver and install so i agreed that they would come in the morning before i left. they delivered the bed but the guys that would assemble was not avail at that point. they kept calling me during the memorial services asking me what time i would be available. i finally compromised and went home to meet them. they assembled the bed and the tore open the mattress packaging to set on bed only to find the bed was not the same size. they left without disassembling the bed and i had to call in on the following Monday to inform HC of this. I spoke to a supervisor(female) who promised to sort this out asap. i finally get a call on 09/02 from a guy from the warehouse informing me they would do exchange the following day. i waited and waited and no calls and no delivery...? so this morning i call in to HC and Amanda takes my call, i was frustrated and wanted to speak to her supervisor and when i did not want to give her my id number she proceeded to put me on hold & her words to me before she put me on hold was "then you will wait". she proceeded to have a coffee/toilet break i presume coz i waited some 5minutes and 40 secs before i dropped the call and called back. Then Elrica Mitchells answered and when i informed her about my incident with Amanda she said that there were a few Amanda's but the 1 I'm enquiring about was not at her desk. how would she know which Amanda i spoke?? Elrica did not care that i was frustrated and did not care that i had a problem, although she works in customer care - she duly put me on hold to get a manager not before muttering that i was an idiot. yes she called me a paying customer and idiot!!? none the less i can say that i will not be dealing with HC ever again and i can tell you i never in all the years that i have with HC never not once received a curtesy call after i called in to express my concerns. the culture the cc agents displayed when representing HC shows that clients do not matter to them unless you are buying something. if you got a complaint they do not know how to deal with clients and the customer care agents believe it is there right to have a job and the customer is a belligerent idiot that receives the item for free! well i am sick and tired and would like to be put in contact with the top brass so that i can fully express my disgust at the representatives and procedures in place.
