UNACCEPTABLE AND BAD CUSTOMER SERVICE FROM TAKEALOT's RETURNS DEPARTMENT

I lodged a return/replacement for an incomplete "TP-Link Wireless Dual Band 4G LTE Router" on 28 May 2020 and received an SMS that it will be collected on 2 June 2020. Till date the item is still with me and there's no prospects of it being collected as some certain Yaseen (after communicating with him via emails) had promised that the item will be collected on 8 June 2020, but that did not happen. I ordered the Router for my online exams which are starting on 15 June 2020. I now have to defer my exams because someone in the Takealot company did not and still is not doing his/her Job. I never had any hustles with my orders save for this one and its costing me my future. Unacceptable customer service!!!!
