Appalling behaviour from Adidas DPD Laser Consultants

If I could give a zero rating for this company, I would give them just that. I purchased Adidas Joggers online which came extremely big in my normal size and I requested to return them. Getting the return label was seamless but DPD keeps sending me messages every day stating they will collect the item and never do. I have spoken to countless people and I am being sent pillar to post. Thembi, the last consultant I spoke abruptly ignored me and was busy talking to her colleagues while I was explaining my situation, the lady before her (Bonolo) deceived in believing she has requested my parcel to be collected from my home address as I will be out of office from tomorrow and Thembi confirmed that she did not and cannot do it. The number of days I have to return this item is expiring soon and I am travelling to another province and these ladies are refusing to help me stating Adidas will contact me directly. As a loyal customer, I am disgusted at the behaviour and service I am getting from Adidas.
