Utterly disgusted, Mountain Mill branch

I am utterly disgusted with the service received from Vodacom Mountain Mill Mall (Worcester). I was at the shop on 8 January 2020 - the sales person gave me her email address and a list of documentation needed for the new data deal application. I sent an email that afternoon - no response. On 9 January I called and I was told she's on leave and I forwarded the email to another sales person. This person entered my next of kin's number as my own, so my father received an sms regarding the vetting process. So I called to change the number; I was told this will be done immediately. No word from Vodacom, so 13 January I called again. I was informed, in an extremely rude manner that the first sales person was not on leave but she was off the 9th (doesn't really matter, fact is she wasn't there); anyway,I was then told they couldn't get a hold of me, the contract has been ready since the previous week (no calls on my phone and no email - so did they, in fact, update my number??). I signed the contract that same day. Yesterday, 15 January, the sim card was activated - FINALLY. After one hour of using the router (which I took on contract), the battery was flat. I tried charging it, but a light kept on flickering and after 30 - 60 minutes it was flat again. This morning I called to follow up on the contract I requested from them yesterday, as I would like to have a copy (the person who assisted me over the phone promised to do it immediate - ppffft) and I asked if they can replace my BRAND NEW router. The lady told me it has to go in for repairs (7 - 10 days) and sorry, they do not have a spare to give me in the mean while. WHAT THE HELL Vodacom?? My partner was going to get one of the contracts now as well and upgrade in March, but we have decided to cancel that contract and he will definitely not get a new one from you.
