Service team and drivers don't communicate and makes it my problem - EVEN WITHIN DAYS APART

BUFEX***JYQ - I asked you as request comes in to change my collection date. Your service takes a day to respond to say great they accept a later date (the following week which is 25 August) on 19 August and ask what time in the morning would suite me. Your drivers still come through on 20th, 21st and 22nd and then cancel the collection. I cannot reset the request to come get my collection done and your service team just says "sorry for me". Never even accepting they were wrong even though it should be on system. I cannot log another request to have it collected and you are just shocking. Your support staff is slow - I asked the morning of 19th on whatsapp group to talk, they respond after 4pm "Hello". I then say I responded on email and yet your service staff keep telling me it is my problem. Driver came on wrong days so my issue. NOW WHAT??!?!?! Your team just says it is my problem. Please get management involved to fix this. Btw - your service staff also told me management will phone, yet still waiting.
