Disgusting service and zero accountability, additional costs to customers

Order no. *** - 25 July 2025, was queried by me on *** as it had not yet "started shopping" at the delivery time, I was told all was in order and to wait. After the delivery time had elapsed I called again and was told there was an issue. The shop had accepted order but not allocated a picker. Over 30 mins later I was called back to say a picker would now be assigned, over an hour after the scheduled delivery date. I requested the order be postponed to the following day as there was no one at home to collect at this new time. I was informed that a Supervisor had messaged the store as the store does not answer their phone and it takes forever to get through. 30 mins later driver called to say he was there. The store then cancelled the order even though they had been requested to postpone it. Order no. *** was placed on the 26 July to replace the previous order. I was promised on numerous occassions that a Supervisor would call me, I am still waiting. I asked for ref no's but was told there were none, I should just use my cell no. as all info was listed under my cellphone no. profile. I was given a voucher "Apologiescoupon50" and told it was valid for 1 month. Today the voucher does not work! the call centre has no trace of me and cannot find my orders or any escalation or any voucher under my cellphone no., order number or name! I need to provide them with the details via email! The amount of time and money wasted on calls alone has not been worth any special, promotiion or convenience of a delivery. Highly not recommended
