Appaling service from Makro,

I placed an order (#MAK***) online on the 24th of August and realised that I had selected a wrong pick-up location of Joburg whilst I am in Cape Town. I phoned the call centre the following day and the agent - Lesego said he was going to inform the relevant department to process the refund despite the payment not reflecting. A partially amount of R116.94 was refunded to my account on the 30th of August. The rest of the balance was not paid. Every time I speak to the agents they say the payment by Makro was rejected. How This is so boggles my mind. I have phone the call centre for up to 5 occasions and asked to submit my ID and bank details. Every time the call agents promise that They will escalate the issue for speedy processing and nothing comes out of this. IN A COMPETITIVE ENVIRONMENT LIKE EXISTS IN THE RETAIL SPACE - MAKRO SHOULD STRIVE TO DO BETTER. THIS APPALING TO SAY THE LEAST!!!!
