Refused to honour Supplier Money Back Guarantee !

I bought a Shaver from Clicks on 25 October 2019 with a 100 day supplier money back guarantee as the product was not working properly. As far as I was concerned this refund should have been made no matter if there was a product issue or not ! On 26 December 2019 morning (within the 100 days) I took it back to Clicks Artem Centre for a refund at approximately 10.10 am. I was told that they did not have enough cash in the till to do the refund. Then I went to Canal Walk for a refund. The Manager said to me "it is protocol to check the problem" and proceeded to show me the instruction manual to say the shaver needs to charge for 90 minutes. I asked what happened to the 100 day money back guarantee and was told that I need to leave the shaver to be checked. I then asked him why Artem Centre was going to refund and asked the Manager to phone Artem Centre. He did not and I phoned the gentleman and the Manager questioned the poor staff member in front of me about protocol, his position, etc. This was extremely unprofessional. I was irate as by this time it was I had wasted over 30 minutes in the store for a simple refund. I then phoned the Clicks Customer Care lined and explained the situation to them. They agreed with about the 100 day money back guarantee and the fact that they would simply send the product back to the supplier for credit. About another hour of going backwards and forwards Customer Care they told me that the Store Manager is in charge and needed to follow his decision. I then decided to phone the V&A Waterfront as I bought the shaver from them. They said to me I must bring it back to the store for credit. Upon arriving at the Waterfront I decided to turn around as the traffic was backed up and I had waited 20 minutes in the traffic to get to the entrance. I went to Clicks in Glengariff Road and met a friendly Manager. He explained to me that he would gladly do the refund but they do not carry this item. He then proceeded to open the box and he noted that the instruction manual and travel pouch was missing. I then phoned the Manager at Canal Walk again and told him I am coming back as no Clicks Branch would accept this return without all the contents. Eventually I arrived at the Canal Walk and I think the Manager was shocked to see me again. He then proceeded to give me a refund without following any "protocol" ! Not sure what changed from the morning to the afternoon ? The time was now 3.00 pm. The Customer Call Line explained to me that it is Public Holiday and he will get an Area Manager to phone me on Friday which did happen. I phoned the Area Manager again on 2 January 2020 and he told me the Canal Walk Manager was on holiday for a few days and was back now (which I understood) but he will be speaking to him and will phone me back in the afternoon. It is Sunday 5 January and still ZERO communication. As a loyal Clicks customer for over 30 years, I will not support them anymore with this pathetic experience !
