Refund Query

I am not sure whether it is TEMU or TYME BANK but between the two someone is giving me a run around.I made few purchases on the 29 April 2025.However I requested for refund when I noticed that I purchased duplicate products.I requestd for a refund on the 17 June 2025.TEMU provided me with the proof refund and stated that my bank instituion will allocate the fund with the next 7-8 business days,meaning I should expect funds on the 26-27 June 2025.However I still did not receive any funds.I contacted TYME BANK on the 30 June 2025.The consulted advise that it was 7-14 working days for TEMU refunds.Therefore I expected the funds on the 7-8 July 2025.They lodge a ticket on my behalf and further requested for the proof of purchase/refund and that I will receive feedback in the next 3 business day.I forwarded same on the 7th July 2025.After the 3 days passed.I contacted them.And they advised they will contact me after 3 days.After 3 days they told me to send the same documents/proof again and feedback will be given with in 3 business days AGAIN.And I still have not received any assistance from Tyme bank until today.I contacted TEMU and they advised that the refund was sent to my bank institution,therefore I need to contact TYME BANK..
