Some companies have bad customer service, others have very bad, you even have companies with no customer service at all, but vodafone customer service,! I got admit they are on a different level, you phone them and if you are able to get a hold of them and manage to speak with somebody after that idiotic answering machine, then you get a nerve massage of 5 min nonsense security questions and when you pass that, you will start explaining your issue like to a 5 year old kid and not to a specialist that is supposed to solve your problem, when he finally understoods about 5% of your exhausting explanation then he will tell you to hold the line and he will transfer you to the right specialist and again the same exhausting explaining and guess what, he understands your problem slightly better then the previous one but he can't really help with the issue because they need a group of specialists to solve the problem!?! Again same explaining procedure and finally after hour and half you get some kind of instructions what to do and a promise that the problem with the ridiculously slow so called 4G will be solved, you hang up relieved from the long nerve chewing conversation and with hope that you've solved your issue. I have followed all the instructions and change to new settings and guess what FiNnally no changes at all, I kid you not , they have dumb, dumber and dumbest for customer service. On the next freaking day I called them again bla bla bla bla 1 hour nonsense and I was promised I would get new sim card the next day that will work 100% and a 20£ discount from next payment, waited for more then a week and finally I have received a blank sim card and when I have plugged it in no network at all nothing like I did not have a sim card at all, I've said to my self im not gonna try anymore and plugged back the old sim with the slow net sim card, my contract was ending the next month on the 10th of august I've got the discount they have promised and was planning to keep it till my contract expires but on the 29th of july 11 days before the contract expires they have blocked my sim card completely and it displays SIM card not provisioned for voice, my banking account was linked to that number i was expecting a really important call from HMRC and they cut me off so effortlessly i couldn't believe it. This is just a very small portion issues that I had with vodafone and I can go on, but Im sure anybody will get the picture about this horror twilight zone company so called vodafone. It is outrageous vodafone should be prosecuted criminally and take away their licence as a provider with a big fine.
