Makro Online appalling service

I placed an online order on the 19th of February and I realised that my address and contact number were outdated, within a few minutes I immediately called the contact centre and they advised the details will be amended and the update will be escalated to the store that will be process my order. On the 20th I received an update sms that order has been handed over to the courier and that was the end of any more communication I never received any further communication, updates or information to track my delivery, I actually called them again on the 20th to confirm if my delivery and contact details were definitely updated and the agent read them aloud to confirm. Then on the 22nd I log in on their website and the status of my delivery says "delivery failed - RTO" then I gave them a call and they advised the courier driver experienced problems with his vehicle and the parcel was being return to the store and they would ask for them to rearrange urgent delivery. Now today I received an email advising that my delivery failed due to being unable to contact me. This is disgusting because I could have just ordered from Takelot and already received my parcel, and I ordered this specifically for work purposes now I have no idea what is going on or when will I receive my delivery. I regret giving Makro online a chance their service is absolutely **********
