Takelot putrid service and delay tactics

Order #*** - On 18th Sept I ordered a UPS for router to keep me connected during loadshedding as my job requires me to work from home full time. It was delivered on the 20th Sept. The same day I scheduled a return via the app as I ordered the 12v instead of the 9v. My mistake and fully accept responsibility. I am informed it will be picked up by the 3rd party courier company on the 22nd. Called takealot again on the 23rd after courier told me they had no instruction to collect. Takelot re-schedules it for pickup on the 27th. Today the 29th still no pickup and and no instruction to courier company. Takelot wants to just reschedule again. I will not be refunded until collected, then from courier hub to Takealot hub and assessed etc which could take another 7 - 10 days after pickup. I cannot order the correct one until refunded. This is unacceptable especially since we have another order here that was delivered but is wrong. We ordered 9kg auto washing powder, they deliver hand wash. Scheduled exchange nearly 3 weeks ago and still has not been collected and when we complained they wanted pics to see what the product is and to determine if they have exchange stock available. Really this is delay tactics as you have my order on the system and can see for yourself what the product is. This after we were given the run around with the exchange too. Service delivery is non-existent. I have never experienced this with Takelot and am now at the end of my tether and escalating options.
